N,N′-(Phenylmethylene)diacetamide analogues which were simply prepared from the condensation reaction of an aldehyde with an amide or urea were found to be efficient ligands in copper-catalyzed coupling reaction of aryl halides with various azole nucleophiles. The newly developed ligand showed broad application scope in this conversion. Compounds including imidazoles, benzoimidazoles, pyrrole, indole, and benzotriazole were successfully arylated with diversified aromatic halides to give corresponding products in moderate to excellent yields.
