Aromatic Chlorosulfonylation by Photoredox Catalysis

ChemSusChem, 2016
AbstractVisible‐light photoredox catalysis enables the efficient synthesis of arenesulfonyl chlorides from anilines. The new protocol involves the convenient in situ preparation of arenediazonium salts (from anilines) and the reactive gases SO2 and HCl (from aqueous SOCl2).
