The significant stability of magnetic core and -OH functional groups on the surface of silica-coated cobalt ferrite (CoFe2O4@SiO2) nanoparticles make it as a good candidate for the functionalization and catalytic application. In this work, a surface-modified magnetic solid support with the Cu (II) complex tags was prepared. The structure of newly prepared nanostructure was characterized by Fourier-transform infrared spectroscopy (FT-IR), X-ray powder diffraction (XRD), thermogravimetric analysis (TGA/DTG), vibrating sample magnetometr (VSM), the field emission scanning electron microscopy (FE-SEM), the electron-dispersive X-ray spectroscopy (EDS), and inductively coupled plasma optical emission spectrometry (ICP/OES) techniques. The catalytic activity of prepared hybrid nanomaterial was evaluated in the synthesis of 1-amidoalkyl-2-naphthols and high yields of desired products obtained under green media. Some advantages of this method are high yields, short reaction times, green solvent and conditions, easy workup procedure, negligible copper leaching, reusability without a significant diminish in catalytic efficiency and simple separation of nanocatalyst by using an external magnet alongside the environmental compatibility and sustainability.
