A photoredox-catalyzed synthesis of α,α-difluoromethyl sulfones from sulfur dioxide with readily available gem–difluoroalkenes is reported. This protocol features mild reaction conditions, broad substrate scope and good functional group compatibility, giving rise to the target α,α-difluoromethyl sulfones in moderate to excellent yields. Mechanistic studies indicate that this reaction is initiated by an aryl radical with the insertion of sulfur dioxide.
