Boron Trifluoride-catalyzed Reaction of Alkyl Fluoride with Silyl Enolate,Allylsilane,and Hydrosilane

摘要

Alkylation of silyl enolates with tert-alkyl or allylic fluorides proceeds smoothly in the presence of a catalytic amount of boron trifluoride to afford the corresponding carbonyl compounds.Allylation and reduction of alkyl fluorides with allylsilane and hydrosilane,respectively,occur under BF_3 catalysis.
