1,1′-binaphthyl-2,2′-diamine dihydrochloride: an efficient ligand for the N-arylation of imidazole with aryl/heteroaryl halides catalyzed by CuI
Employing 1,1′-binaphthyl-2,2′-diamine(BINAM) dihydrochloride as an efficient and commercially available ligand, relatively mild and highly efficient copper-catalyzed coupling reactions of imidazole with aryl and heteroaryl halides have been developed. Various N-arylimidazoles could be synthesized in moderate to excellent yields.
