Trifluoromethylthiolation/oxidation of styrenes with easiy-handling AgSCF3 used as the trifluoromethylthiolating reagent has been described, which furnished a series of α-trifluoromethylthio acetophenons. A variety of substituted styrene could be bifunctionalized via radical process in a mixed solvent of dimethyl sulfoxide (DMSO) and CHCl3, with potassium persulfate used as the oxidant under mild conditions. A simple and efficent method for the facile construction of various α-trifluoromethylthio acetophenons is thus demonstrated.

Key words: styrene, trifluoromethylthiolation, radical
