A copper-catalyzed mono-lateral protosilylation of dialkynylphosphine oxides for the synthesis of β-silyl substituted vinylphosphine oxides is described. Various (hetero)aryl and alkyl-substituted diynes afforded the corresponding products in moderate and high yields with high chemoselectivity. An alternative alkynyl functional group of products could also be further derived.

Key words: copper catalyst, protosilylation, phosphine oxides, β-silyl substituted compounds
