Abstract

A facile one-pot C-benzylation of various sodium enolates derived from methyl malonate, β- ketoesters, a β-cyanoester, a β-cyanosulfone, ketones and a carboxylic ester is reported. Reaction of alkoxydiphenylsulfonium salts formed by treating various benzyl alcohols with diphenyl sulfide bis (trifluoromethanesulfonate)(derived from trifluoromethanesulfonic anhydride and diphenyl sulfoxide) proceeded smoothly, and the corresponding C- ...
