The synergistic effect of zinc and copper in Cu2O/ZnO nanoflake as a heterogeneous catalyst for the N-arylation of heterocycles with aryl halides and arylboronic acids in the absence of additional ligand in air were demonstrated. The catalyst was characterized by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), BET surface area measurement, and FT-IR spectroscopy.

N-(1-Oxy-pyridin-2-ylmethyl)oxalamic acids (L3-L5) were identified as novel efficient ligands for copper-catalyzed C-N cross-coupling of azoles and aryl halides 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 water-sensitive materials. The catalytic mechanism was proposed based on the results of several verification experiments which indicated that the ligands as new-type chelators may coordinate to Cu(i) with two oxygen atoms of N-oxide and amide in the coupling process.
