Conjugate addition of the phenyldimethylsilyl group to αβ-unsaturated carbonyl compounds using a silylzincate in place of the silylcuprate

Abstract

Lithium phenyldimethylsilyl(dialkyl)zincates add to a number of αβ-unsaturated carbonyl compounds to give, in most cases, higher yields of the conjugate addition product than we had achieved with the corresponding silylcuprate.
