Stereoselective synthesis of vinylsilanes via copper-catalyzed silylation of alkenes with silanes.

An efficient and stereoselective synthesis of vinylsilanes via copper-catalyzed direct silylation of alkenes with silanes was developed. This study offers a new and expedient strategy for the synthesis of synthetically useful alkenyl organosilicon compounds in satisfactory yields and may provide a low-cost and environmentally benign alternative to currently employed precious metal systems for alkene silylation. Moreover, the transformation is proposed to proceed via a radical process and exhibits a broad substrate scope and good functional group tolerance.
