摘要

A simple strategy avoiding the decomposition of a naked trifluoromethyl anion to difluorocarbene by a sterically very demanding organo-superbase without the help of a trifluoromethyl anion reservoir such as DMF is reported. The direct non-metallic trifluoromethylation of carbonyl compounds using fluoroform in the presence of t-Bu-P4 base afforded trifluoromethyl alcohols in high yields.
