▎ 摘　　要

In this study, copper(II)-coordinated 5,10,15,20-tetrakis(aminophenyl)porphyrin (CuPPh) as a macrocyclic copper complex was covalently linked to the surface of graphene oxide (GO-CuPPh). This covalently cross-linked catalyst was characterized with various analysis such as FT-IR, SEM, TEM, EDS, ICP, TGA and UV-Vis. All analysis confirm the successful covalently immobilization of CuPPh on the GO. Then, the activity of catalyst has been tested for the preparation of propargylamine derivatives by the reaction of different aldehydes/ketones various amines and phenylacetylene via A(3) and KA(2) coupling reactions. The catalytic system indicated great catalytic activity in this reaction and the yields of the products were good to marvelous. The results of this work are hoped to aid the establishment of new class of heterogeneous catalysts as the high performance and low-cost candidates for industrial applications. [GRAPHICS]
