Synthesis of dibenzo[a,c]carbazoles from 2-(2-halophenyl)-indoles and iodobenzenes via palladium-catalyzed dual C–H functionalization

Abstract

An efficient palladium-catalyzed strategy for the synthesis of dibenzo[a,c]carbazole derivatives has been developed. In the presence of Pd(OAc)₂, 2-(2-halophenyl)-indoles and iodobenzenes proceeded smoothly to obtain the corresponding dibenzo[a,c]carbazoles in moderate to good yields. This methodology constructs two new C–C bonds via a palladium-catalyzed dual C–H functionalization.
