Research paper (scientific journal) Joint Exploring Full Catalytic Cycle of Rhodium(I)-BINAP Catalyzed Isomerisation of Allylic Amines: A Graph Theoretical Approach of Path Optimisation Takayoshi Yoshimura, Satoshi Maeda,* Tetsuya Taketsugu, Masaya Sawamura, Keiji Morokuma,* Seiji Mori Chemical Science RSC publishing 8/ 6, 4475-4488 2017/04 10.1039/C7SC00401J We explored the reaction mechanism of the cationic rhodium(I)–BINAP complex catalysed isomerisation of allylic amines using the artificial force induced reaction method with the global reaction route mapping strategy, which enabled us to search for various reaction paths without assumption of transition states. The entire reaction network was reproduced in the form of a graph, and reasonable paths were selected from the complicated network using Prim’s algorithm. As a result, a new dissociative reaction mechanism was proposed. Our comprehensive reaction path search provided rationales for the E/Z and S/R selectivities of the stereoselective reaction.

Am. Chem.

  4. Research paper (scientific journal) Joint Theoretical Studies of Rhodium-Catalyzed Borylation of Nitriles through Cleavage of Carbon-Cyano Bonds Hirotaka Kinuta, Hiroaki Takahashi, Mamoru Tobisu, Seiji Mori, and Naoto Chatani Bull. Chem. Soc. Jpn 87/ 6, 655-669 2014/04/07 10.1246/bcsj.20130332 Rhodium(I)-catalyzed borylation of nitriles is investigated theoretically, using the density functional theory method, to clarify the reaction mechanism, including the formation process of the catalytically active species, carbon-carbon bond cleavage, and the effect of an amine additive. The initial step in this reaction is the formation of a borylrhodium(I) species, in which the rhodium center carries a significant negative charge. The most energetically favorable pathway for carbon-carbon bond cleavage involves the insertion of a cyano group into borylrhodium(I) to form an iminoacyl intermediate, followed by extrusion of boryl isocyanide (iminoacyl mechanism). The calculation suggests that DABCO can react with coproduced reactive boron species, such as boryl chloride and boryl isocyanide, to form stable adducts, lowering the energy of the entire reaction system. In addition, the chemoselectivities among C-CN, C-Br, and C-Cl bonds observed in experimental studies are in good agreement with the calculated activation energies required for these bond activation processes.
  5. Research paper (scientific journal) Joint Density Functional Studies on Isomerization of Prostaglandin H2 to Prostacyclin Catalyzed by Cytochrome P450 Tetsuya K. Yanai, Seiji Mori Chem. Eur. J. 15/ 17, 4464-4473 2009/04/20 At the double: DFT studies on the biosynthesis of prostacyclin (PGI2, see scheme) from prostaglandin H2 (PGH2) show two reaction mechanisms through two different oxidation states, an FeIV-porphyrin intermediate and an FeIII-porphyrin pi-cation radical, followed by a proton-coupled electron-transfer process. Reaction mechanisms for the isomerization of prostaglandin H2 to prostacyclin catalyzed by cytochrome P450 are investigated by the unrestricted Becke's three-parameter plus Lee-Yang-Parr density functional level of theory. The results show that the homolytic OO bond cleavage of endoperoxide in prostaglandin H2 is the rate-limiting step and that the isomerization proceeds through proton-coupled electron transfer. We located two reaction pathways through an FeIV-porphyrin intermediate and an FeIII-porphyrin pi-cation radical intermediate.
