Recently, the preparation of fluorinated compounds through difunctionalization strategies has become a hot research area in fluorine chemistry. In this work, a copper-catalyzed hydroxytrifluoromethylthiolation of arylpropynones for the synthesis of the corresponding trifluoromethylthiolated enols was developed. The copper salt and solvent are crucial to the yields of this reaction. Under optimized reaction conditions, a series of trifluoromethylthiolated enols were obtained in moderate to good yields.

Key words: copper, trifluoromethylthiolation, hydroxylation, propynone, radical
