Herein we disclosed a one-pot two-step protocol for the first direct, base-catalyzed α-trifluoromethylthiolation of carboxylic acid derivatives by using readily available N-acyl pyrazoles, N-(trifluoromethylthio)phthalimide and a nucleophile such as amines, alcohols and water. Straightforward elaboration of the products to alcohols and triflones expands further the synthetic utility of the process.
