Rhodium(II)-Alkynyl Carbenoids Insertion into Si-H bonds: An Entry to Propargylic Geminal Bis(silanes)

摘要

alpha-Alkynyl-alpha'-trimethylsilylhydrazones are used as novel Rh(II)-carbenoids precursors. These new carbenoids have shown very good reactivity in Si-H insertion reactions, leading to original propargylic geminal-bis(silanes) in a two-step sequential process.
