Silver–copper co-catalyzed cascade intramolecular cyclization/desulfinamide/dehydrogenation: one-pot synthesis of substituted carbazoles.

Herein, a silver and copper co-catalyzed cascade intramolecular cyclization/desulfinamide/dehydrogenation reaction for the synthesis of substituted carbazoles is reported. This reaction, which involved formation of new C–C and C–N bonds as well as C–N bond cleavage, afforded diverse carbazoles in high yields and showed good functional group tolerance.
