摘要:
In this work, a new heterogeneous catalyst based on 1,2,3-triazole complex of copper supported on core-shell Fe3O4@SiO2 nanoparticles was designed and characterized by using several methods such as infrared spectroscopy (FTIR), X-ray diffraction (XRD), thermogravimetry analysis (TGA), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and energy-dispersive X-ray spectroscopy (EDX). The magnetic nanocatalyst was successfully employed for the synthesis of different functionalized 3,4-dihydropyrimidin-2(1H)-ones/thiones by a one-pot multicomponent condensation reaction under solvent-free conditions. Among the advantages of the developed catalytic protocol are the high yields, short reaction times, ecofriendly, easy workup and purification conditions.
