Regio- and stereoselective hydrosilylation of alkynes with alkoxysilanes for the synthesis of β-(Z) vinylsilanes catalyzed by a dirhodium(ii)/XantPhos complex

Abstract

A Rh₂(OAc)₄/XantPhos ((9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphane)) catalyzed regio- and stereoselective hydrosilylation of alkynes with various tertiary silanes in acetonitrile represents a straightforward and highly effective strategy for the synthesis of β-(Z) vinylsilanes. This method exhibits remarkable compatibility with diverse functional groups, encompassing halides, nitriles, amines, esters, nitro compounds, and heterocycles.
