Abstract

In recent years, attention has been paid to using recyclable nanocatalysts as heterogeneous catalysts in producing organic compounds. In this research, an eco-friendly synthesis of amido alkyl naphthols is described from the reaction of β-naphthol and various aromatic aldehydes, amides, and amines by using magnetic Iron oxide nanoparticles (Fe3O4 NPS), Zinc Oxide nanoparticles (ZnO NPS), and Copper Oxide nanoparticles (CuO NPS) as heterogeneous catalysts. The structure of products was studied using characterization techniques such as Fourier Transform Infrared Analysis (FTIR), 13CNMR, and 1HNMR. The reusability of the catalyst for this synthesis has been studied for at least four runs without significant loss of their activities.
