چکیده

In this study, a facile and efficient method for the synthesis of 5-amino-7-aryl-4,7-dihydro-[1,2,4]triazolo[1,5-a]pyrimidine-6-carbonitrile based on alginate/pumice copper-catalyzed multicomponent reaction of a triazole with aryl aldehyde is reported in the presence of malononitrile in ethanol. A new heterogeneous and recyclable nanocatalyst based on copper iodide supported on functionalized pumice has been introduced for this target. The synthetic process of the mentioned nanocatalyst, Cu@Fe3O4/alginate/pumice, has been described [1-3]. The characterization of the Cu@Fe3O4/alginate/pumice was afforded by TEM, SEM, EDS, FTIR, ICP, and XRD. The surface structure of the materials was confirmed using Fourier transform infrared (FTIR) spectroscopy.
