Photo-induced FeCl3-catalysed direct desulfurative chlorination of thiol-containing aromatics at room temperature

Abstract

We report herein an FeCl₃-catalyzed desulfurative chlorination of thiol-containing aromatics at room temperature under near visible light irradiation. This study demonstrates that FeCl₃ can effectively catalyze the direct chlorination of a variety of commercially available or readily accessible thiol-containing aromatics under ambient conditions, with irradiation at 395–400 nm, resulting in the corresponding aryl chlorides.
