It has been found that the final products of the reaction of sulfonyl chlorides and tertiary amines in the presence of cadmium sulfide nanoparticles under visible light irradiation are highly dependent on the applied reaction conditions. Interestingly, with the change of a reaction condition, different pathways were conducted (visible-light-induced N-dealkylation or sp3 and sp2 C–H activation) that

The synthesis of diaryl sulfones derivatives through Friedel-Crafts sulfonylation was achieved by using trifluoromethanesulfonic acid as catalyst with arylsulfonyl chlorides and arenes at elevated temperatures. In this procedure, the catalyst and the surplus of arene may well be retrieved and recycled in further batches.
