identified as novel efficient ligands for copper-catalyzed C–N cross-coupling of azoles and arylhalides in water. The N-arylation of imidazoles, indoles and pyrazoles proceeded with moderate to excellent yields and complete selectivity over aromatic amines and phenols. Moreover, L5, which is also efficient in organic solvent with low catalyst loading, can be used to promote the N-arylation reactions with
