Abstract
We report, herein, a photoinduced iron-catalyzed direct chlorination of aromatic sulfonyl chloride at room temperature. In this protocol, FeCl 3 -catalyzed direct chlorination has been realized at room temperature under the irradiation of light (400–410 nm). During the process, many commercially or readily available substituted aromatic sulfonyl chlorides could produce the corresponding aromatic chlorides in moderate to good yields.
