Abstract: | A new and heterogeneous copper complex immobilized on graphene oxide (GO) was prepared. This was achieved through organic functionalization of GO using 1,8-diamino-3,6-dioxaoctane (DADO) and then inorganic coordination of copper on the edges and basal plane of the functionalized GO (GO-DADO-Cu), which was reduced to Cu(0). The chemical structure of the prepared nanocatalyst was analyzed using various techniques. Most of the analyses confirmed the successful anchoring of copper and organic ligand on the GO surface. Moreover, the synthesized nanocatalyst has shown high catalytic activity in the synthesis of β-hydroxy-1,2,3-triazole derivatives under mild reaction conditions (water and room temperature) resulting in good to excellent yields. |
