A new method has been developed for the copper(I)-mediated trifluoromethylthiolation of α-bromoketone using commercial anhydrous potassium fluoride, elemental sulfur, and (trifluoromethyl)-trimethylsilane in anhydrous N,N-dimethylformamide. This protocol provides facile access to a variety of α-trifluoromethylthiolated carbonyl compounds in moderate to excellent yields under mild and ligand free conditions.
