Cu nano particles supported on graphene oxide nano sheets (CuNPs@GO) for novel synthesis of N-(phenyl(4-phenyl-1H- 1,2,3-triazol—yl) methyl)benzamine

Graphene oxide supported nanometals such as Cu, Ag, Pd , … has been used as a heterogeneous catalyst for the synthesis of 1, 2, 3- triazoles[1,2]. In this work we hope to use CuNPs@GO as an efficient catalyst in the synthesis of N-(phenyl(4-phenyl-1H-1,2,3-triazol—yl) methyl)benzamine from the the reaction of sodium azide,terminal alkynes, and different imines in H2O as a green solvent at room temperature. The CuNPs@GO were characterized by FT-IR, CHN, TGA, ICP, XRD, SEM,TEM techniques, successfully.The activity of the prepared catalyst was tested for the synthesis of N-(phenyl(4-phenyl-1H-1,2,3-triazol—yl) methyl) benzamine via click chemistry reactions which lead to the desired products in high yields and short reaction time.
