An efficient, general, inexpensive, and environmentally friendly photosynthesis of sulfonamides via visible light promoted debenzylative sulfonylation of tertiary benzylamines is described. Compared to the traditional S?N coupling reactions, which are promoted by oxidative C?N bond cleavage of symmetrical tertiary alkylamines, this strategy provides a selective C?N bond cleavage protocol and avoids the use of transition-metal, explosive oxidants, and ligands.

A catalyst-free, charge-transfer complex promoted coupling of sulfonyl chlorides with vicinal tertiary diamines to generate sulfonamides is presented. Mechanistic studies showed that these reactions are proceeded via charge transfer of vicinal tertiary diamines to sulfonyl chlorides, forming the unstable sulfonyl quaternary ammonium like complexes which induced the regiospecific intramolecular C?N bond cleavage of vicinal tertiary diamines. (Figure presented.).
