Rhodium(III)‐Catalyzed [3+2]/[5+2] Annulation of 4‐Aryl 1,2,3‐Triazoles with Internal Alkynes through Dual C(sp²)H Functionalization

Abstract

Abstract A rhodium(III)‐catalyzed [3+2]/[5+2] annulation of 4‐aryl 1‐tosyl‐1,2,3‐triazoles with internal alkynes is presented. This transformation provides straightforward access to indeno[1,7‐ cd ]azepine architectures through a sequence involving the formation of a rhodium(III) azavinyl carbene, dual C(sp 2 )H functionalization, and [3+2]/[5+2] annulation.
