平田竜士君、豊増智也君が中心となって行った担持Au触媒を用いた芳香族sp2 C-H結合シリル化に関する研究成果がChemCatChem 誌 (Wiley)にAcceptされました。Our paper reporting electrophilic C(sp2)-H silylation by supported gold catalysts was accepted in ChemCatChem (Wiley).

Heterogeneous gold-catalyzed C(sp 2 )-H silylation is described. A variety of heteroarenes and electron-rich arenes participated in gold-catalyzed silylation to afford the corresponding heteroaryl and arylsilanes in good to excellent yields. A detailed mechanistic investigation corroborated that the cooperative catalysis of ether and O 2 -activated gold nanoparticles realized heterolysis of the Si-H bond to generate silyl cations, which enabled subsequent electrophilic C-Si bond formation. The high activity, reusability and environmentally-friendly nature of the heterogeneous gold catalysts as well as the scalability of the reaction system realize the sustainable synthesis of aryl and heteroarylsilanes.
