Photo-induced copper-catalyzed controllable de-nitrogen/SO2 insertion of aryltriazenes: Divergent synthesis of aryl sulfonamides and diaryl sulfones

A photo-induced copper-catalyzed nitrogen extraction/SO 2 insertion of aryltriazenes for the controllable synthesis of aryl sulfonamides and diaryl sulfones has been established. Under purple LED irradiation, using CuI as catalyst and...
