“…40 Recently, some of the nanoparticles have been used as catalysts for the synthesis of heterocyclic compounds. [41][42][43][44][45] Continuing our work on catalytic reactions, [46][47][48][49] we would like to report here on the preparation of NiCoFe 2 O 4 NPs as nanocatalysts for the four-component synthesis of tri-substituted imidazoles from benzil and aromatic aldehydes with ammonium acetate under solvent-free conditions.…”

In this study, NiCoFe2O4 nanoparticles were prepared and used as a reactive catalyst for the synthesis of trisubstituted imidazoles. The multicomponent reactions of aromatic aldehydes, benzil and ammonium acetate were carried out under solvent-free and conventional heating conditions. In this reaction, some imidazole derivatives with high purity, short reaction times and high yields were obtained. The prepared nanocatalyst was characterized by FT-IR, XRD, EDX, VSM and SEM techniques. Moreover, the organic products were identified by melting point, FT-IR and 1H NMR analyzes.

“…In continuance of our team research to prepare the GO as a support catalyst, [33][34][35][36] we hope to prepare ZnO NPs@rGO nanocomposites through a simple method and their application for synthesis of dihydropyrimidinone derivatives under solvent free and mild conditions. The catalyst recovered six times without loss of its activity and play significant role in catalyst on the basis of our knowledge.…”

In this research, it was presented a simple and easy method for the preparation of graphene oxide (GO) supported ZnO nanoparticles with low cost, available precursor and their application as nanocatalyst for synthesis of l,4-dihydropyirimidinones. When GO combines with metal oxide nanoparticles such as ZnO shows very good properties. There is a wide range of chemical methods for the attachment of various functional groups. In this protocol, the GO was synthesized through Hummer's method. The structure and morphology properties of ZnO NPs@rGO nanocomposite were investigated by Fouriertransform infrared spectroscopy, X-ray diffraction, scanning electron microscopy, and energy-dispersive X-ray spectroscope techniques. Also, the organic compounds were identified by melting point, FT-IR, and proton nuclear magnetic resonance analyses.
