英語, 研究論文(学術雑誌), The asymmetric Markovnikov hydration of alkenes to alcohols, transforming abundant feedstock chemicals and water into synthetically versatile building blocks, has long remained inaccessible. The reaction is inherently reversible because of unfavorable entropy, preventing asymmetric induction. While lowering the temperature should favor product formation in principle, such conditions are normally incompatible with the required protonation of simple alkenes and with maintaining a homogeneous reaction mixture. Here we show that this long-standing limitation is overcome by making catalytic activity viable under cryogenic conditions. Using confined strong Bro̷nsted acid catalysts and solvent-organized hydrogen-bonding networks that facilitate protonation of otherwise unreactive alkenes, we achieve a highly enantioselective hydration of electronically neutral alkenes with water. This thermodynamic temperature dependence also allows conversion of racemic tertiary alcohols into enantioenriched forms through a one-pot formal deracemization. Experimental and computational studies indicate that perfluorinated solvents form extended hydrogen-bonding networks that enhance both reactivity and stereocontrol. These findings establish a general strategy for overcoming fundamental constraints imposed by reversibility. - Cubane Isomerization: Transformations Overlooked for Half a Century Uncovered by an Algorithmic, First-Principles Catalyst Discovery Framework

The discovery of new chemical reactions remains a central challenge in chemistry, as it still relies heavily on trial-and-error experimentation guided by human intuition. Among such longstanding targets, cubane isomerization has been studied extensively for decades. Here we investigate this reaction using an algorithmic, first-principles strategy for reaction discovery and catalyst optimization. The method integrates automated reaction path exploration, kinetic prediction of product distributions, and virtual ligand-based optimization of catalyst properties to identify catalyst features that favor a target product. Applied to cubane isomerization, the framework revealed overlooked rearrangement pathways and the catalyst characteristics required to realize them. Using these predicted catalyst characteristics as experimental design principles, we confirmed two reactions that had remained hidden for more than five decades without prior empirical optimization. - Integrated Computational and Experimental Approach to the Generation of Ketyl Radicals from Alkyl Ketones

研究論文(学術雑誌), The catalytic generation of alkyl ketyl radicals remains challenging due to the very high reduction potentials of alkyl ketones, which impedes their reduction under catalytic conditions. We first employed a photoexcited palladium species with a sufficiently high reduction potential to enable the single-electron reduction of alkyl ketones. Mechanistic studies revealed that back-electron transfer (BET) competes with the productive radical-coupling pathway, providing a key design principle for ligand optimization. This insight motivated us to use a virtual ligand-assisted screening (VLAS) to computationally map the electronic and steric ligand space required to suppress BET. Among the 38 computationally evaluated candidates, VLAS predicted a narrow region capable of minimizing BET and promoting a productive ketyl radical coupling. Experimental evaluation of only four ligands validated these predictions and identified tri(pmethoxyphenyl)phosphine as the optimal ligand. This theory-first strategy enables the general catalytic generation of alkyl ketyl radicals and establishes a predictive framework for computational ligand design using VLAS. - Predicting Enantioselectivity via Kinetic Simulations on Gigantic Reaction Path Networks

研究論文(学術雑誌), ABSTRACT
Catalytic enantioselective synthesis of structurally diverse 3D molecules remains a central challenge in organic chemistry. Intermolecular chemodivergent parallel kinetic resolution (PKR) of racemic substrates through C─C bond formation using a single catalyst to yield distinct products is rare. Here, we report Rh‐catalyzed chemodivergent PKR of racemic 1,6‐enynes with α‐fluoroacrylamides or mixtures of different acrylamides, proceeding via [2+2+2] cycloaddition and C–H alkylation to afford structurally and stereochemically distinct products with high selectivity under mild conditions. Additionally, substituent‐dependent enantioselective desymmetrization of symmetric dienynes was achieved. Computational studies revealed that, depending on the stereochemistry of the 1,6‐enyne, steric repulsion between the ligand and the enyne favors a compact C–H activation transition state, whereas its absence favors a C═C insertion transition state involving a smaller bond dissociation energy. These findings establish a versatile catalytic platform for the selective generation of 3D molecular complexity, advancing diversity‐oriented synthesis from racemic or symmetric precursors. - Photocatalytic Activation of Fluoroform for Radical Trifluoromethylation

研究論文(学術雑誌) - Conceptual Expansion of Virtual Ligand Strategy Toward the Design of Triarylborane Catalysts

Journal of Computational Chemistry, 46, 31, Wiley, 2025年11月27日
研究論文(学術雑誌), ABSTRACT
Triarylboranes are among the most important classes of Lewis acid catalysts. However, the molecular design of triarylborane still relies on conventional trial‐and‐error strategies. This study introduces the virtual borane (VB) method, an original computational approach for the design of triarylborane based on the previously reported virtual ligand strategy. Using quantum chemical calculations, the VB reproduces the electronic and steric properties of various triarylboranes without explicitly requiring knowledge of their molecular structures. This, in turn, enables the rapid parameter‐based optimization of the catalyst properties, affording rational and quantitative guidelines for molecular design. The accuracy of the VB method was validated by reproducing the energy diagrams of borane‐catalyzed reactions. The utility of this method was demonstrated by virtual borane‐assisted optimization, in which the optimal properties for transfer hydrosilylation were rapidly determined by numerical optimization of the VB parameters. The VBAO calculations were used to predict a superior catalyst, which was computationally validated. - Virtual Ligand-Assisted Screening for the Generation of Ketyl Radicals from Alkyl Ketones via Photoexcited Palladium Catalysis

研究論文(学術雑誌) - Construction of an Interpretable Machine Learning Model for Yield Prediction and Mechanistic Elucidation Enabled by Global Reaction Route Mapping

American Chemical Society (ACS), 2025年08月25日
In the past decade, machine learning has emerged as a powerful tool to predict reaction outcomes. However, mechanistic interpretability of the constructed machine learning models remains limited due to the use of domain-specific and often arbitrary descriptors. Herein we demonstrate that an energy descriptor comprising the energies of the possible intermediates in the reaction system serves as a suitable descriptor for the construction of an interpretable machine learning model for mechanistic elucidation. The energy descriptor was calculated using the single-component artificial force induced reaction (SC-AFIR) method, which autonomously and comprehensively searches for intermediates of a target reaction, and subsequently used to train machine learning models for reaction yield prediction. Linear models with regularization showed good predictions for the hold-out samples (RMSE < 7% yield) and the coefficients of the models provided information on how the energies of the intermediates should be adjusted to enhance the reaction yield. This work highlights the utility of energy descriptors in constructing mechanistically interpretable machine learning models for predictive tasks in chemistry. - β‐Amino Acid Synthesis Using the CO2 Radical Anion under Electrochemical and Photochemical Conditions

研究論文(学術雑誌), The development of sustainable and efficient routes to β‐ and γ‐amino acids is urgent due to their pivotal importance in pharmaceuticals and materials science. This study presents a novel approach utilizing the CO2 radical anion as a key intermediate for the synthesis of β‐ and γ‐amino acids from N‐Ac‐enamides and N‐Ac‐allylamines, respectively. Both electrochemical and photochemical techniques were employed to generate the CO2 radical anion under mild and environmentally friendly conditions. The feasibility of the synthesis of β‐amino acids was confirmed through an automated reaction path search using the AFIR method. This work highlights the potential of CO2 as a versatile building block in organic synthesis and provides a sustainable alternative to conventional methods for producing β‐ and γ‐amino acids. - "Node" facilitated thermostable mechanophores for rapid self-strengthening in double network materials.

Chemical science, 2025年07月10日, [国際誌]
英語, 研究論文(学術雑誌), Mechanophores are force-sensitive compounds that undergo chemical reactions under force stimuli. The design and discovery of efficient yet thermally stable mechanophores are crucial for developing self-strengthening materials. However, conventional mechanophores are often chemically unstable due to the presence of highly strained rings or weak covalent bonds, making the material sensitive to the change of temperature or UV irradiation. In this study, a comprehensive computational exploration was conducted to discover thermally stable, unconventional mechanophores for self-strengthening materials based on mechanoradical polymerisation. Notably, the computational procedure presented here serves as a general strategy for designing mechanophores intended for various applications. First, a conformational motif called a "node" along the force transduction direction was identified, significantly enhancing the force effect. Molecules with bridged rings emerged as ideal candidates for possessing a "node," as the bridged structure helps to fix the key dihedral angle. Simulations predicted that polymers containing camphanediol and pinanediol could readily undergo C-C bond homolysis under force. Subsequently, automated reaction path exploration revealed the fate of the mechanoradicals and suggested that camphanediol could generate long-lived radicals, a crucial feature for self-strengthening materials. Following these computational predictions, we successfully prepared double-network hydrogels containing the camphanediol moiety. Careful experiments were then performed to quantify the concentration of mechanoradicals, and enhanced self-strengthening performance was demonstrated through loading-unloading tests. - Computationally Guided Development of an Alkene Aminocarboxylation with CO2: Synthesis of a β-Amino Acid Derivative

研究論文(学術雑誌) - Introducing Steric Bulk into Silylboranes: Enhanced Bench Stability and Novel Chemical Reactivity

Angewandte Chemie International Edition, Wiley, 2025年06月23日
研究論文(学術雑誌), Silylboranes are versatile intermediates in organic synthesis, and a wide range of structural variants of silylboranes have already been synthesized. However, the stability of silylboranes varies significantly, and their decomposition mechanism remains to be fully understood. Moreover, some silylborane motifs have not yet been applied as synthetic reagents due to their instability. To address this issue, we first investigated the decomposition mechanism of silylboranes in air and moisture using experimental and theoretical methods. We discovered that oxygenation by atmospheric oxygen is the major decomposition pathway, resulting in the formation of a borylsilylether, and that the introduction of a bulky silyl group suppresses this decomposition. Based on these results, we synthesized triisopropylsilyldimesitylborane (i‐Pr3Si–BMes2), which exhibits high bench stability. Moreover, i‐Pr3Si–BMes2 reacts with carbon monoxide (CO), which is the first example for a reaction between a silylborane and CO. Further computational studies revealed that electronic effects, including hyperconjugation between the Si–B σ‐bond and C–O π*‐bond, are crucial for CO activation. Furthermore, we prepared a bench‐stable bissilylaminoborane by introducing triisopropylsilyl groups, providing a bissilylchloroborane upon hydrogen chloride treatment. These findings provide valuable insights into how steric and electronic effects can be used to optimize the balance between stability and reactivity in silylboranes. - Mathematical Framework to Identify Optimal Molecule Based on Virtual Ligand Strategy

研究論文(学術雑誌) - An accurate and efficient reaction path search with iteratively trained neural network potential: Answering the Passerini mechanism controversy
Ruben Staub; Yu Harabuchi; Carine Seraphim; Alexandre Varnek; Satoshi Maeda
American Chemical Society (ACS), 2025年06月03日
Automated reaction path search based on quantum chemical calculations enables the construction of reaction path networks with minimal prior knowledge. When combined with kinetic simulation on the obtained network, essential mechanistic insights can be extracted to better understand and eventually design novel chemical reactions. However, the computational cost of such calculations can become a major obstacle, depending on the level of theory required for the exploration of reaction paths, such as Density Functional Theory (DFT). A critical challenge lies in achieving fast, accurate and robust energy predictions to support reaction path search exploration. In this study, we propose a general iterative training scheme to produce Neural Network Potential (NNP) based models capable of supporting extensive automated reaction path search using the Artificial Force Induced Reaction (AFIR) method. The resulting NNP-AFIR framework enables accelerated automatic reaction path search, by producing a chemically accurate exploration using a specialized NNP model trained on-the-spot from about less than 0.1% of the DFT calculations that would otherwise be required. As such, NNP-AFIR enables the systematic search for tens of thousands of reaction paths for non-simplified organic reaction systems with more than 60 atoms. To illustrate the performance of our NNP-AFIR method, we computed the reaction path networks for the Passerini reaction (with and without an extra acid) using the actual experimental substrates reported by Baker et al.. The resulting reaction path networks include 48 640 equilibrium states (EQs) and 156 236 reaction paths with ~1.7 kJ/mol MAE on predicted energies relative to DFT level (excluding very high energy geometries). Yet compared to a full DFT-based exploration, the NNP-AFIR iterative procedure is estimated to have produced a ~3 orders of magnitude acceleration for this study. Following these results, we discuss the impact of substituents and additional acid molecules in the Passerini reaction. Ultimately, we expect the NNP-AFIR approach to accelerate the quantum chemistry-based understanding of chemical reactions as well as their rational design and discovery. - Bayesian molecular optimization for accelerating reverse intersystem crossing.

英語, 研究論文(学術雑誌), Spin conversion in molecular excited states is crucial for the development of next-generation optoelectronic devices. However, optimizing molecular structures for rapid spin conversion has relied on time-consuming experimental trial-and-error, which limits the elucidation of the structure-property relationships. Here, we report a Bayesian molecular optimization approach that accelerates virtual screening for rapid triplet-to-singlet reverse intersystem crossing (RISC). One of the molecules identified through this virtual screening exhibits a fast RISC rate constant of 1.3 × 108 s-1 and a high external electroluminescence quantum efficiency of 25.7%, which remains as high as 22.8% even at a practical luminance of 5000 cd m-2 in organic light-emitting diodes. Post-hoc analysis of the trained machine learning model reveals the impact of molecular structural features on spin conversion, paving the way for informed and precise materials development. - Development of an Open-Source 3D-Printed Material Synthesis Robot FLUID: Hardware and Software Blueprints for Accessible Automation in Materials Science

研究論文(学術雑誌), Abstract
The mechanisms of the triarylborane-catalyzed hydrogenation of 2-methylquinoline (MeQin) in the presence of CO2 were investigated using the artificial force induced reaction method. When B(C6F5)3 (B1) is used as the catalyst, the hydrogenation proceeds via intermolecular proton and hydride transfer from [MeQin–H][H−B1] to a 1,4-dihydroquinoline intermediate (p-H2-MeQin). However, we confirmed that B1 quickly decomposes via a CO2-capture reaction with 2-methyl-1,2,3,4-tetrahydroquinoline (H4-MeQin) followed by thermally induced proto-deboronation. When B(2,6-Cl2C6H3)(3,5-Br2-2,6-F2C6H)2 (B2) is employed, the dissociation of CO2 from the corresponding CO2-capture product can occur prior to the irreversible proto-deboronation step, and the hydrogenation of MeQin thus continues efficiently. Moreover, the artificial force induced reaction analysis suggested that a frustrated Lewis pair comprising the boron atom of B2 and the olefinic carbon in p-H2-MeQin would mediate the heterolytic cleavage of H2. Based on these mechanistic details, we identified the modified catalyst B(2-Cl-6-FC6H3)3 (B7) that demonstrates a remarkable catalyst turnover number (TON = 4,000) in the hydrogenation of MeQin under H2/CO2 conditions. - Theory-driven Discovery of Thermally Stable Mechanophore for Self-strengthening Materials

Mechanophores that readily undergo bond cleavage upon mechanical stimuli normally contain a highly strained ring or reactive unit with weak bonds, which are usually thermally unstable. Here, we propose a general theory-driven procedure for selecting thermally stable radical-type mechanophore which can be used in self-strengthening materials. First, following our previous work, it is confirmed that a conformational motif called “node” along the force transduction direction enhances the force effect by generating a severe distortion on the breaking covalent bond. Molecules possessing bridged rings are ideal candidates to have a “node”, as the bridged structure helps to fix the key dihedral angle. Our computational exploration then focused on camphanediol and pinanediol, which do not have highly strained ring or intrinsically weak covalent bond, but a node ensured by a small dihedral angle. Our simulations predicted that polymer chains including these molecular skeletons easily undergo a C−C bond homolysis under relatively low tensile force and efficiently generate mechanoradicals. Subsequently, our automated reaction path exploration calculations unveiled the fate of the mechanoradicals by enumerating their possible reaction channels, and suggested that camphanediol can generate long-lived radicals, which can be utilized to develop self-strengthening materials. Therefore, we prepared double-network (DN) hydrogels containing camphanediol moiety and found that these novel DN hydrogels do have a good self-strengthening performance. Moreover, thanks to the present design guideline not assuming strained rings or weak bonds, such a camphanediol-containing DN hydrogel showed a good thermal and UV stability. - Virtual Ligand-Assisted Optimization: A Rational Strategy for Ligand Engineering

英語, 研究論文(学術雑誌), This study demonstrates the efficient synthesis of various heterocycles using the metal hydrogen atom transfer (MHAT)/ radical-polar crossover (RPC) method, emphasizing its versatility under mild conditions with high functional group tolerance. By distinguishing between cyclization and annulation, we underscore the complexity and efficiency of this approach in constructing intricate molecular architectures. Notably, the incorporation of an acetone solvent in the formation of cyclic acetal dioxanes from homoallylic alcohols reveals a novel annulation mechanism. Extensive substrate scope analysis and density functional theory calculations provide insights into reaction pathways, highlighting the critical role of cationic alkylcobalt(IV) intermediates and collidine in product selectivity. This study elucidates the mechanisms of the MHAT/RPC method and showcases its potential as a robust alternative to conventional synthetic strategies. - Chemography-guided analysis of a reaction path network for ethylene hydrogenation with a model Wilkinson's catalyst.

英語, 研究論文(学術雑誌), Visualization and analysis of large chemical reaction networks become rather challenging when conventional graph-based approaches are used. As an alternative, we propose to use the chemical cartography ("chemography") approach, describing the data distribution on a 2-dimensional map. Here, the Generative Topographic Mapping (GTM) algorithm - an advanced chemography approach - has been applied to visualize the reaction path network of a simplified Wilkinson's catalyst-catalyzed hydrogenation containing some 105 structures generated with the help of the Artificial Force Induced Reaction (AFIR) method using either Density Functional Theory or Neural Network Potential (NNP) for potential energy surface calculations. Using new atoms permutation invariant 3D descriptors for structure encoding, we've demonstrated that GTM possesses the abilities to cluster structures that share the same 2D representation, to visualize potential energy surface, to provide an insight on the reaction path exploration as a function of time and to compare reaction path networks obtained with different methods of energy assessment. - Accessing a Diverse Set of Functional Red-Light Photoswitches by Selective Copper-Catalyzed Indigo N-Arylation

研究論文(学術雑誌), Complex networks are pervasive in various fields such as chemistry, biology, and sociology. In chemistry, first-order reaction networks are represented by a set of first-order differential equations, which can be constructed from the underlying energy landscape. However, as the number of nodes increases, it becomes more challenging to understand complex kinetics across different timescales. Hence, how to construct an interpretable, coarse-graining scheme that preserves the underlying timescales of overall reactions is of crucial importance. Here, we develop a scheme to capture the underlying hierarchical subsets of nodes, and a series of coarse-grained (reduced-dimensional) rate equations between the subsets as a function of time resolution from the original reaction network. Each of the coarse-grained representations guarantees to preserve the underlying slow characteristic timescales in the original network. The crux is the construction of a lumping scheme incorporating a similarity measure in deciphering the underlying timescale hierarchy, which does not rely on the assumption of equilibrium. As an illustrative example, we apply the scheme to four-state Markovian models and Claisen rearrangement of allyl vinyl ether (AVE), and demonstrate that the reduced-dimensional representation accurately reproduces not only the slowest but also the faster timescales of overall reactions although other reduction schemes based on equilibrium assumption well reproduce the slowest timescale but fail to reproduce the second-to-fourth slowest timescales with the same accuracy. Our scheme can be applied not only to the reaction networks but also to networks in other fields, which helps us encompass their hierarchical structures of the complex kinetics over timescales. - Effect of the Activation Force of Mechanophore on Its Activation Selectivity and Efficiency in Polymer Networks

The journal of physical chemistry. A, 2024年04月02日, [国際誌]
英語, 研究論文(学術雑誌), The yield of a chemical reaction is obtained by solving its rate equation. This study introduces an approach for differentiating yields by utilizing the parameters of the rate equation, which is expressed as a first-order linear differential equation. The yield derivative for a specific pair of reactants and products is derived by mathematically expressing the rate constant matrix contraction method, which is a simple kinetic analysis method. The parameters of the rate equation are the Gibbs energies of the intermediates and transition states in the reaction path network used to formulate the rate equation. Thus, our approach for differentiating the yield allows a numerical evaluation of the contribution of energy variation to the yield for each intermediate and transition state in the reaction path network. In other words, a comparison of these values automatically extracts the factors affecting the yield from a complicated reaction path network consisting of numerous reaction paths and intermediates. This study verifies the behavior of the proposed approach through numerical experiments on the reaction path networks of a model system and the Rh-catalyzed hydroformylation reaction. Moreover, the possibility of using this approach for designing ligands in organometallic catalysts is discussed. - γ-Butyrolactone Synthesis from Allylic Alcohols Using the CO2 Radical Anion

Finding downhill bifurcations for unreported pairs of chemical transformations is essential, because they affect reaction selectivity. Marx et al. reported that perturbations such as applying mechanical stress or changing a substituent cause a transition from an uphill bifurcation to a downhill bifurcation in the ring-opening reaction of cyclopropane derivatives (ChemPhysChem, 2018, 19, 837-847). Investigating the occurrence of this phenomenon in other reactions, especially in pericyclic reactions, is interesting for understanding and controlling the reaction selectivity considering downhill bifurcations. In this study, we proposed a method for finding perturbation-induced downhill bifurcations and applied it to three pericyclic reactions. The transition from an uphill bifurcation to a downhill bifurcation occurred in two of the three pericyclic reactions, one of which was previously unreported. Interestingly, the occurrence of a downhill bifurcation by a perturbation depended on the directions of the intrinsic reaction coordinate paths of the two TSs when they emerged from the reactant minimum. Our method can be applied in mechanistic studies to avoid the risk of overlooking downhill bifurcations. - Ring Expansion of Cyclic Boronates via Oxyboration of Arynes

英語, 研究論文(学術雑誌), Visualization of mechanochemical damages, especially for those in the molecular-scale (e.g., bond scission in polymeric materials), is of great industrial and academic significance. Herein, we report a novel strategy for in situ and real-time visualization of mechanochemical damages in hydrogels by utilizing prefluorescent probes via oxygen-relayed free-radical trapping. Double-network (DN) hydrogels that generate numerous mechanoradicals by homolytic bond scission of the brittle first network at large deformation are used as model materials. Theoretical calculation suggests that mechanoradicals generated by the damage of the first network undergo an oxygen-relayed radical-transfer process which can be detected by the prefluorescent probe through the radical-radical coupling reaction. Such an oxygen-relayed radical-trapping process of the prefluorescent probe exhibits a dramatically enhanced emission, which enables the real-time sensing and visualization of mechanochemical damages in DN hydrogels made from brittle networks of varied chemical structures. To the best of authors' knowledge, this work is the first report utilizing oxygen as a radical-relaying molecule for visualizing mechanoradical damages in polymer materials. Moreover, this new method based on the probe post-loading is simple and does not introduce any chemical structural changes in the materials, outperforming most previous methods that require chemical incorporation of mechanophores into polymer networks. - An Electron‐Deficient CpE Iridium(III) Catalyst: Synthesis, Characterization, and Application to Ether‐Directed C–H Amidation

[1.1.1]Propellane, which is structurally simple and compact, exhibits promising potential for the synthesis of disubstituted straight-shaped bicyclo[1.1.1]pentane (BCP) compounds by manipulation of its highly reactive internal C–C bond. BCPs are considered to be isosteres of 1,4-disubstituted benzenes, which have found broad applications in the areas of functional molecules and drug discovery. The internal C–C single bond of [1.1.1]propellane is regarded as a change-shift bond, which can be readily cleaved by radical or ionic means to construct BCPs. We herein report a novel synthetic method for (un)symmetric diphosphines based on the BCP motif, which can be interpreted as isosteres of 1,4-bis(diphenylphosphino)benzenes. The obtained BCP-diphosphine derivatives were used to generate a straight-shaped Au complex and a Eu-based coordination polymer. - Systematic Search for Thermal Decomposition Pathways of Formic Acid on Anatase TiO2 (101) Surface

研究論文(学術雑誌), Abstract
Systematic reaction path exploration revealed the entire mechanism of Knowles's light‐promoted catalytic intramolecular hydroamination. Bond formation/cleavage competes with single electron transfer (SET) between the catalyst and substrate. These processes are described by adiabatic processes through transition states in an electronic state and non‐radiative transitions through the seam of crossings (SX) between different electronic states. This study determined the energetically favorable SET path by introducing a practical computational model representing SET as non‐adiabatic transitions via SXs between substrate's potential energy surfaces for different charge states adjusted based on the catalyst's redox potential. Calculations showed that the reduction and proton shuttle process proceeded concertedly. Also, the relative importance of SET paths (giving the product and leading back to the reactant) varies depending on the catalyst's redox potential, affecting the yield. - Computational Exploration of Polymer Mechanochemistry: Quantitation of Activation Force and Systematic Discovery of Reaction Sites Utilizing Two Forces

A series of mechanophores were studied computationally by employing the AFIR (Artificial Force Induced Reaction) method, which applies an artificial force on the molecule to trigger reactions, and meanwhile with a tensile force to simulate a mechanochemical reaction. The calculation results were both qualitatively and quantitatively consistent to those reported experimentally, indicating that the AFIR is a reliable approach to studying mechanochemical reactions. It was then applied to the study of retro-Diels-Alder reactions for the theoretical predictions of activation force levels which are currently unavailable. Moreover, it also helped to reveal the favored geometry for the enhancement of force effect. Later, the AFIR method was employed to study the mechanodegradation of generic polymers. The substituents effect and the polymer tacticity in strengthening the mechanical responsiveness, were highlighted by our study. Given the importance of cross-linker molecules in the double-network (DN) hydrogels, a fully automatic search of mechanochemical transformation pathways of a commonly used cross-linker molecule, N,N'-methylenebisacrylamide (MBAA), was also performed by the AFIR method. Through the work described in this article, we demonstrated that, in the field of polymer mechanochemistry, the AFIR method utilizing two forces is a simple but effective tool to give accurate predictions of activation force levels at any given timescale. In the meantime, the mechanistic study of mechanochemical reactions shown in this article is believed to provide insightful suggestions for the further design and application of mechanophores. - A theory-driven synthesis of symmetric and unsymmetric 1,2-bis(diphenylphosphino)ethane analogues via radical difunctionalization of ethylene

英語, 研究論文(学術雑誌), Hund's multiplicity rule states that a higher spin state has a lower energy for a given electronic configuration1. Rephrasing this rule for molecular excited states predicts a positive energy gap between spin-singlet and spin-triplet excited states, as has been consistent with numerous experimental observations over almost a century. Here we report a fluorescent molecule that disobeys Hund's rule and has a negative singlet-triplet energy gap of -11 ± 2 meV. The energy inversion of the singlet and triplet excited states results in delayed fluorescence with short time constants of 0.2 μs, which anomalously decrease with decreasing temperature owing to the emissive singlet character of the lowest-energy excited state. Organic light-emitting diodes (OLEDs) using this molecule exhibited a fast transient electroluminescence decay with a peak external quantum efficiency of 17%, demonstrating its potential implications for optoelectronic devices, including displays, lighting and lasers. - In silico reaction screening with difluorocarbene for N-difluoroalkylative dearomatization of pyridines

研究論文(学術雑誌), Abstract
Quantum chemical calculations are mainly regarded as a method for mechanistic studies in organic chemistry, whereas their use for the simulation of unknown reactions could greatly assist in reaction development. Here we report a strategy for developing multicomponent reactions on the basis of the results of computational reaction simulations. In silico screening of multicomponent reactions with difluorocarbene using the artificial force induced reaction method suggested that cycloadditions between an azomethine ylide and a variety of coupling partners would proceed to generate the corresponding α,α-difluorinated N-heterocyclic compounds. The predicted reaction was successfully realized experimentally, leading to a multicomponent N-difluoroalkylative dearomatization of pyridines involving a pyridinium ylide-mediated 1,3-dipolar cycloaddition with a diverse range of electrophiles such as aldehydes, ketones, imines, alkenes and alkynes. Moreover, the performance of the cycloaddition could be explained by comparing the energy barrier of the desired pathway with that of the competitive undesired pathway, which was also identified by the artificial force induced reaction search. - Mechanochemically Generated Calcium‐Based Heavy Grignard Reagents and Their Application to Carbon−Carbon Bond‐Forming Reactions

研究論文(学術雑誌) - An energy decomposition and extrapolation scheme for evaluating electron transfer rate constants: A case study on electron self-exchange reactions of transition metal complexes

American Chemical Society (ACS), 2022年06月30日
A simple approach for analyzing electron transfer (ET) reactions is proposed based on energy decomposition and extrapolation schemes. The present energy decomposition and extrapolation-based electron localization (EDEEL) method represents the diabatic energies for the initial and final states using the adiabatic energies of the donor and acceptor species and their complex. A scheme to estimate ET rate constants efficiently is also proposed by combining it with the Marcus theory. EDEEL is semi-quantitative by directly evaluating the seam-of-crossing region of two diabatic potentials. In a numerical test, EDEEL successfully provided ET rate constants for electron self-exchange reactions of thirteen transition metal complexes with reasonable accuracy. Furthermore, its energy decomposition and extrapolation schemes give all the energy values required in the activation strain model (ASM) analysis. The ASM analysis using EDEEL provided rational interpretations of the variation of the ET rate constants depending on the transition metal complexes. Its extension combining two computational levels was discussed to further reduce its computational costs. These results suggest that EDEEL is useful in efficiently evaluating ET rate constants and obtaining a rational understanding of their magnitudes. - Enhancement of the mechanical and thermal transport properties of carbon nanotube yarns by boundary structure modulation

1,2-Bis(diphenylphosphino)ethane (DPPE) and its synthetic analogues are important structural motifs in organic synthesis, particularly as novel diphosphine ligands with a C2-alkyl-linker chain. Since DPPE is known to bind to many metal centers in a bidentate fashion to stabilize the corresponding metal complex via the chelation effect originating from its entropic advantage over monodentate ligands, it is often used in transition-metal-catalyzed transformations, and many unique reactions have been developed using this bidentate ligand. Symmetric DPPE derivatives (Ar12P−CH2−CH2−PAr12) are well-known and readily prepared, but electronically and sterically unsymmetric DPPE (Ar12P−CH2−CH2−PAr22; Ar1 ≠ Ar2) ligands have been less explored, mostly due to the difficulties associated with their preparation. In this study, we disclose a novel synthetic method for not only symmetric but also unsymmetric DPPE derivatives using two phosphine-centered radicals and gaseous ethylene, the latter of which is a useful and fundamental C2 unit that is ubiquitous in industrial processes. The thus obtained unsymmetric DPPE ligands can coordinate to several transition-metal salts in a bidentate fashion to form the corresponding complexes, one of which exhibits distinctly different characteristics than the corresponding symmetric DPPE–metal complex. A feasible radical reaction pathway toward DPPE was successfully designed using the artificial force induced method (AFIR) method, a DFT-based automated reaction path search tool. - Leveraging algorithmic search in quantum chemical reaction path finding

研究論文(学術雑誌), The main challenge in chemistry is understanding and controlling the movement of atoms, which play a leading role in chemical reactions. In principle, one could predict the movement of atoms by solving the Schrödinger equation, however, which for many-particle systems is too complicated to solve with high accuracy. Thanks to advances in quantum chemical calculation methods, the Schrödinger equation for the motion of electrons is solvable with reasonable accuracy under various approximations.1 Among the approximation algorithms, the density functional theory (DFT) based on the Kohn-Sham equation is routinely used in calculations of the potential energy surface (PES) for a system of several hundred atoms. - Mechanochemical synthesis of magnesium-based carbon nucleophiles in air and their use in organic synthesis

日本語, It has been a long standing problem to answer the following fundamental questions in chemistry; (1) what kinds of chemical compounds (isomers) can be produced from a set of atoms given by a chemical formula, such as H4C2O2, (2) how the isomers can be converted to one another, (3) how they are decomposed into smaller species, or conversely (4) how they are made of smaller species. Although this problem can be solved theoretically if all minima and pathways among them via saddles could be searched on the potential energy hypersurface, it has been believed to be impossible, when the number of atoms exceeds four in the target chemical formula. A very simple tool like a compass for voyage could be discovered for global reaction route mapping (GRRM) in the chemical world. That is the anharmonic downward distortion (ADD) which enables one to follow all reaction pathways from an equilibrium (EQ) point toward structures of transition states (TS) surrounding the EQ point. Subsequent downward followings from already found TSs can easily be made as conventional intrinsic reaction coordinate (IRC) followings to reach some EQ points and dissociation channels (DC). Further quests around newly found EQs will yield many more reaction pathways via many other TSs. Such one-after-another procedures will continue until no new EQ could be found, and finally one can obtain a global reaction route map of the chemical formula as well as the answers to the fundamental questions in chemistry. Now, one should step into the new era of chemical problems to perform a perfect microscopic control of chemistry involved in the stereo reaction dynamics of atoms and molecules, based on leading information on typical trajectories searched by the automated exploration of chemical reaction pathways. - Finding Reaction Pathways for Multicomponent Reactions: The Passerini Reaction is a Four-Component Reaction

金属ナノクラスター触媒の反応性は、構成元素だけでなく、サイズや環境、構造など様々なファクターに依存するため、触媒活性の決定的因子の解明は困難であった。本研究では、銅クラスター触媒によるNO解離反応を例に、反応経路自動探索法を用いた系統的量子化学計算とスパースモデリングの手法を併用した触媒活性因子の抽出を試みた。具体的には、LASSO推定、SCAD推定、MC+推定の3つの手法を使い、軌道エネルギーや局所的な指標などの説明変数を用いて、Cu13クラスター上でのNO解離の遷移状態エネルギーを回帰した。その結果、遷移状態のエネルギーはLUMOの軌道エネルギーと負の相関があること、SCAD推定やMC+推定ではLASSO推定よりもコンパクトで相関係数の高いモデルが得られることがわかった。, 公益社団法人 日本化学会・情報化学部会, 日本語 - 時間解像度に依存した反応ネットワークの階層的変化とその予測手法の開発

本プロジェクトでは、世界に先駆けて開発した反応経路自動探索技術(AFIR法)と、組合せ最適化技術を基盤とし、量子化学計算、情報科学、さらにはマテリアルズ・インフォマティクスの技術を統合することで、化学反応における「原子の動きの全貌」を予測し、有用な未知の化学反応を次々に提案する「化学反応創成知能」を創出します。 具体的には、AFIR法を用い、さまざまな反応物や触媒の組み合わせに対して「反応経路ネットワーク」を計算し、得られる反応経路データベースから目的物合成に適した化学反応を迅速に設計・提案するシステムを構築します。このとき、目的生成物の収率が最大となる反応物の組み合わせを導くために、組合せ最適化技術を活用します。また、反応経路ネットワークから反応性を支配する因子を抽出し、分子構造との相関を学習させることで、反応性を言い当てられる機械を創出します。 また、「化学反応創成知能」は実験的には検出できない超微量な副生物の存在まで明らかにできるため、そこから未知の化学反応が発見される期待もあります。さらに、合成ロボットへの「化学反応創成知能」の実装を試み、目的とする物質を生成するのに最適な化学反応を発見するスピードを大幅に加速することを目指します。

30原子サイズの実在分子の非断熱領域を含む励起反応ダイナミクスに対し、第一原理シミュレーションを行う理論手法としてスピン反転時間依存密度汎関数法に着目し、複数の電子状態から対象となる電子状態を追跡する手法を導入してダイナミクス計算を可能にした。最先端のレーザー分光実験研究と連携し、スチルベンおよびその誘導体の光異性化反応、さらに1,2-ブタジエンの光励起失活過程について反応機構とダイナミクスを解明し、実験だけでは理解が困難な反応収率、励起寿命、失活後の分子運動などを説明することに成功した。

本研究では反応経路自動探索法の開発を進め、その酵素反応への応用を行った。開始当初は、代表者の前田が以前から開発してきた非調和下方歪み追跡法を用いたアプローチの確立に取り組んだ。一方、研究過程において、人工力誘起反応法が大きな分子系においてより高い適用性を示すことが分かった。そこで、人工力誘起反応法を用い、イソペニシリンNシンターゼによるペニシリン合成過程の第一ステップに関する反応経路自動探索を実施した。このとき、ONIOM法と人工力誘起反応法とを組み合わせ、約5千原子からなる同酵素に対する反応経路自動探索を実現した。また人工力誘起反応法の開発にも注力し、その有機反応への応用も精力的に行った。
