A new silica supported copper N-heterocyclic carbene (Cu-NHC@SiO2) complex is prepared and characterized by scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX) and X-ray photoelectron spectroscopy (XPS) analyses. This complex is an efficient and easily retrievable catalyst for 1,2,3-triazole synthesis through direct azide-alkyne cycloaddition reaction as well as one-pot reaction using arylboronic acids. This catalytic system is also suitable for synthesis of 4-aryl-NH-1,2,3-triazoles from diverse benzaldehydes. Further, the catalyst can efficiently be recycled up to fifth cycle for all the three methods of 1,2,3-triazole synthesis through direct azide-alkyne cycloaddition and multi-component reactions.

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.
