  • Selective Monoarylation of Aromatic Ketones via C-H Bond Cleavage by Trialkylphosphine Ruthenium Catalysts

    Suzuki I., Kondo H., Kochi T., Kakiuchi F.

    Journal of Organic Chemistry (Journal of Organic Chemistry)   2019

    ISSN  00223263

     View Summary

    © 2019 American Chemical Society. A catalyst system consisting of RuHCl(CO)(PiPr3)2, CsF, and a styrene derivative was found to be applicable to selective monoarylation of aromatic ketones via ortho C-H bond cleavage. The reaction of 2′-methoxyacetophenone with arylboronates gave C-H arylation products without cleaving the ortho C-O bond. Acetophenone was also converted to monoarylation products with high selectivity. Cyclohexanone was found to be an effective solvent for the C-H arylation using the catalyst system.

  • Nondissociative chain walking as a strategy in catalytic organic synthesis

    Kochi T., Kanno S., Kakiuchi F.

    Tetrahedron Letters (Tetrahedron Letters)  60 ( 37 )  2019.09

    ISSN  00404039

     View Summary

    © 2019 Elsevier Ltd “Nondissociative” chain walking is a mechanism where an alkylmetal species undergoes rapid β-hydride elimination and reinsertion to move the metal center along the alkyl chain without dissociating an alkene intermediate during the migration process. This digest summarizes the unique characteristics of the nondissociative chain walking mechanism compared to the stepwise alkene isomerization mechanism and their use in catalytic organic synthesis.

  • Iron-Catalyzed Ortho-Selective C−H Alkylation of Aromatic Ketones with N-Alkenylindoles and Partial Indolylation via 1,4-Iron Migration

    Kimura N., Kochi T., Kakiuchi F.

    Asian Journal of Organic Chemistry (Asian Journal of Organic Chemistry)  8 ( 7 ) 1115 - 1117 2019.07

    ISSN  21935807

     View Summary

    © 2019 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim An ortho-selective C−H alkylation of aromatic ketones with N-alkenylindoles proceeded in the presence of just a Fe(PMe3)4 catalyst. In addition, C−H indolylation products, which are considered to be formed via 1,4-iron migration, were also observed as minor products.

  • Synthesis of N-Arylpyrazoles by Palladium-Catalyzed Coupling of Aryl Triflates with Pyrazole Derivatives

    Onodera S., Kochi T., Kakiuchi F.

    Journal of Organic Chemistry (Journal of Organic Chemistry)  84 ( 10 ) 6508 - 6515 2019.05

    ISSN  00223263

     View Summary

    © 2019 American Chemical Society. A method for the synthesis of N-arylpyrazoles by palladium-catalyzed coupling of aryl triflates with pyrazole derivatives is described. Using tBuBrettPhos as a ligand, the palladium-catalyzed C-N coupling of a variety of aryl triflates including ortho-substituted ones with pyrazole derivatives proceeded efficiently to give N-arylpyrazole products in high yields. 3-Trimethylsilylpyrazole was found to be an excellent pyrazole substrate for the coupling, and the corresponding product, 1-aryl-3-trimethylsilylpyrazole, also served as a great template for the syntheses of N-arylpyrazole derivatives, as demonstrated by regioselective halogenation at the 3-, 4-, and 5-positions of the pyrazole ring.

  • Metal-Catalyzed Sequential Formation of Distant Bonds in Organic Molecules: Palladium-Catalyzed Hydrosilylation/Cyclization of 1,n-Dienes by Chain Walking

    Kochi T., Ichinose K., Shigekane M., Hamasaki T., Kakiuchi F.

    Angewandte Chemie - International Edition (Angewandte Chemie - International Edition)  58 ( 16 ) 5261 - 5265 2019.04

    ISSN  14337851

     View Summary

    © 2019 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim Sequential formation of distant bonds in organic molecules was achieved for the palladium-catalyzed hydrosilylation/cyclization of various 1,n-dienes by chain walking of the metal catalyst. The reaction was applicable to various 1,n-dienes, including a 1,13-diene, to form a cyclopentane ring as well as a carbon–silicon bond at a remote site. The use of “nondissociative” chain walking provides a fascinating strategy in organic synthesis to functionalize distant parts of organic molecules, in a particular order, within a catalytic cycle by effectively moving the reactive center from a remote position.
