For the simultaneous preparation of molecules having both the nucleophilic and electrophilic sites, allyl trimethylsilyl ethers as electrophilic allylating reagents are studied. Allyl trimethylsilyl ethers react with allyl trimethylsilanes in the presence

α-(Sulfenylmethyl)allyl acetates reacted with silylated carbon nucleophiles in the presence of a catalytic amount of TMSOTf to give products substituted at the α-position of the sulfenylmethyl group in moderate to good yields with high regioselectivity.The theoretical calculation on an intermediate cationic species indicated that an episulfonium ion was a stable form; the observed regioselectivity was rationalized qualitatively on the basis of the coefficients of LUMO of the cation.Some transformations of the products were also demonstrated.

(α-Sulfenylmethyl)allyl acetates reacted with sil]ylated carbon nucleophiles in the presence of a catalytic amount of a Lewis acid to give mainly α-adducts at the sulfenylmethyl group in moderate to good yields with high regioselectivity. The reaction may
