Nucleophilic trifluoromethylation of non-enolizable and enolizable carbonyl compounds was achieved with the trifluoromethanesulfinamide derived from O-silylated ephedrine. In contrast to the trifluoroacetamide analog, previously described, this reagent is able to trifluoromethylate more acidic enolizable compounds.
