The present study describes the synthesis and characterization of a new poly(N-heterocyclic carbene Cu complex) immobilized on nano silica, (CuII-NHCs)n@nSiO2. The (CuII-NHCs)n@nSiO2 dendritic polymer was characterized by FT-IR, TGA, UV-vis, FE-SEM, TEM and ICP-OES techniques. The catalytic activity of this new catalyst was studied in the synthesis of benzimidazoles I (Ar = 2-MeC6H4, 3-BrC6H4, 4-ClC6H4, etc.), benzothiazoles II, 1,2,3-triazoles III (R1 = H, 2-Br, 4-Cl, etc.), bis-triazoles and Sonogashira-Hagihara cross-coupling reactions. The (CuII-NHCs)n@nSiO2 heterogeneous catalyst showed the advantages such as high efficiency, good to excellent yield, short reaction times, easy separation and high reusability of the catalyst.
