Abstract

An organic Lewis base promoted direct difluoromethylation reaction of carbonyl compounds with Me3SiCF2H has been studied. The Schwesinger's superbase can efficiently activate the Si–CF2H bond and initiate the difluoromethylation of aldehydes and ketones under very mild conditions, producing difluoromethyl adducts in 42–99% yields.
