Abstract

Synthesis of efficient and reusable catalyst was carried out by immobilizing azacrown ether onto the covalently linked amine-functionalized mesoporous MCM-41 via a simple method. Application of this linked azacrown ether functionalized MCM-41 catalyst was also investigated as an effective, heterogeneous in the synthesis of hexahydroquinoline derivatives under solvent-free conditions at environment temperature. The heterogeneous catalyst is characterized by TGA, XRD, TEM, 1HNMR, 13CNMR, and FT-IR techniques. The results of theses analysis showed that, MCM-41@azacrown-SB-Cu catalyst with a 22.99% mol loading of copper has given excellent catalytic activity and high efficiency in a short time. It is noted that one of the most valuable factors in this work is the recyclability of the catalyst.
