Palladium-catalyzed C–H bond activation for the assembly of N-aryl carbazoles with aromatic amines as nitrogen sources†
Abstract
A convenient and efficient palladium-catalyzed C–H bond activation for the assembly of N-aryl carbazole is reported, in which two C–N bonds were formed under one set of conditions. The desired carbazoles were achieved in decent yields with a wide substrate scope by utilizing readily available 2-iodo biphenyls and aromatic amines as starting materials.
