An efficient method for the chemoselective and desulfurative Chan–Lam cross-coupling based on benzimidazoline-2-thiones was developed. By modulating the amount of the catalyst Cu(OAc)2·H2O, alkali, temperature, and solvent, the desulfurizational C–N bond formation product (N-arylbenzimidazoles) could be selectively furnished smoothly. The features of this protocol are an inexpensive and readily available catalyst, ligand-free conditions, wide substrate scope, easy performance, and moderate to excellent yields. It shows potential synthetic value for the preparation of a diversity of arylbenzoheterocyclic compounds, which are potentially active in pharmaceuticals and agrochemicals.

An efficient method for the copper-catalysed arylation of nitrogen-containing heterocycles is reported using 3-(diphenylphosphino) propanoic acid as a ligand in combination of CuCl. The C-N coupling reactions afford various N-arylated products in good to excellent yields.
