The preparation of 4-trimethylsilyl-2-butenoate trimethylsilyl ester and 1,1-bis(trimethylsiloxy)-1,3-butadiene are described.The latter silyl derivative reacts with benzaldehyde in the presence of ZnBr2 in THF to give exclusively γ-substituted product (E configuration) in high yield.The fluoride ion catalyzed reaction affords predominantly α-alkylated compounds.
