Abstract

Effective research in green chemistry requires new and applicable synthetic techniques. In this regard, for the first time, a green method is reported for the immobilization of iminodiacetic acid–Ni complex on the surface of CoFe2O4 magnetic nanoparticles. The obtained nanocomposite was characterized via chemical and physical techniques such as Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), energy-dispersive X-ray analysis (EDX), inductively coupled plasma-optical emission spectrometry (ICP-OES), scanning electron microscopy (SEM), X-ray mapping and thermal gravimetric analysis (TGA) techniques. In addition, catalytic activity of the as-prepared nanocomposite was examined in the synthesis of polyhydroquinoline and bis(pyrazolyl)methane derivatives in green conditions. It was observed that all the products were obtained during short reaction time and in good to excellent yields. Importantly, the catalyst was easily recovered and recycled by magnetic field for five successive times without noticeable decrease in its catalytic activity.
