Polystyrene and silica gel-supported, AlCl3-catalyzed preparation of diaryl sulfoxides from arenes and thionyl chloride
A simple, chemoselective, and efficient method has been developed for direct conversion of arenes to symmetrical diaryl sulfoxides using thionyl chloride in the presence of a catalytic amount of cross-linked polystyrene-supported aluminium chloride (Ps-AlCl3) and silica gel-supported aluminium chloride (SiO2-AlCl3). These solid acid catalysts are stable and can be easily recovered and reused without appreciable change in their efficiency. Copyright Taylor & Francis Group, LLC.
