Here, we have reported fabrication of graphitic polymeric C3N4 supported CuCl2 (Cu@g-C3N4) and characterized by powder X-ray diffraction, field emission scanning electron microscopy, high resolution transmission electron microscopy, X-ray photoelectron spectroscopy studies. An efficient and regioselective protocol for the on water synthesis of 4-aryl-NH-1,2,3-triazole derivatives via 1,3-diipolar cycloaddition reactions of nitroolefins/phenylacetylenes to sodium azide were demonstrated by using Cu@g-C3N4 as robust and reusable catalyst.

4-Aryl-NH-1,2,3-triazoles are valuable compounds in organic chemistry and pharmaceutical chemistry. In this paper, we describe a novel multicomponent reaction of aldehydes, nitroalkanes, and sodium azide for the synthesis of 4-aryl-NH-1,2,3-triazoles. In this transformation, it was found that both the slow addition of nitroalkane and the presence of NaHSO3/Na2SO3 are advantageous to promote the reaction results. Additionally, a series of aldehydes and nitro compounds were investigated.
