Two visible-light mediated protocols (based on a copper photoredox catalyzed and on a photochemical reaction, respectively) for the preparation of aryl thiocyanates and aryl selenocyanates from arylazo sulfones are presented herein, by exploiting the peculiar photoreactivity and redox activity of such substrates. The developed reactions take place in good to satisfactory yields and with a large scope
