Hydrosilylation of Terminal Alkynes with Alkylidene Ruthenium Complexes and Silanes

Abstract

[reaction: see text] Ruthenium alkylidene complexes 1-3 mediate hydrosilylation of alkynes with silanes. When triethoxy- or triphenylsilanes are used as silylating agents, the reaction affords alpha-substituted vinylsilanes as major products.
