Abstract :

In this study, considering the importance of nanocatalysts in organic reactions, a copper salen complex supported on cobalt ferrite–hydroxyapatite magnetic nanoparticles(CoFe₂O₄@HAP@Cu Salen Complex) was synthesized and characterized using various techniques including FT-IR, SEM, ICP, XRD, etc. The activity of the catalyst in a multicomponent reaction was investigated for the synthesis of spirooxindole derivatives, and high-yield products were prepared. The absence of toxic solvents, easy recycling and reusability of the catalyst, and no formation of by-products are the advantages of this method.
