Trifluoromethyl benzoate (Phenyl trifluoroacetate, Benzoyl triflate, Benzoesaeuretrifluormethylester, TFBz) is a new, easily-prepared, shelf-stable and versatile reagent for nucleophilic trifluoromethoxylation reaction with broad scope of substrates. Its synthetic potency is demonstrated by trifluoromethoxylation-halogenation of arynes, nucleophilic substitution of alkyl (pseudo)halides, cross-coupling with aryl stannanes, and asymmetric difunctionalization of alkenes. etc.. The unprecedented trifluoromethoxylation-halogenation of arynes proceeds smoothly at room temperature with the aid of a crown ether-complexed potassium cation, which significantly stabilize the trifluoromethoxide anion derived from TFBz.
