Nano Copper(I) Oxide/Zinc Oxide Catalyzed N-Arylation of Nitrogen-Containing Heterocycles with Aryl Halides and Arylboronic Acids in Air.

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.
