Selective Formation

A mild, practical, and environmentally friendly route to vinyl sulfones and sulfonamides has been developed based on the reaction of aliphatic amines with arenesulfonyl chlorides in the presence of eosin Y as a photocatalyst under visible light. The method permits the selective formation of vinyl sulfones or sulfonamides, depending on the oxidation environment and solvent. A wide range of products were obtained in moderate to good yields under the optimized conditions.
