A copper-catalyzed three-component coupling reaction of azoles, Se powder, and aryl iodide is described for the first time. This transformation provides a straightforward and facile pathway to synthesis 2-arylselanyl-azoles via a copper-catalyzed double C–Se bonds formation process. This reaction is attractive and practical since the cheap copper catalyst is employed and it does not require ligands, proceeds in generally good yields, and has a broad range of functional groups tolerance.
