N2 - Ni0.5Cu0.5Fe2O4 magnetic nanoparticles using Arabic gel (AG) as a reducing and stabilizing agent was prepared by the sol-method. The catalyst identification was performed using Fourier transform infrared spectroscopy (FT-IR), powder X-ray diffraction (PXRD), scanning electron microscopy (SEM), and vibrating sample magnetometer (VSM). The magnetic analysis showed that the Ni0.5Cu0.5Fe2O4 had a ferromagnetic behavior with a saturation magnetization of 31.22 emu/g at room temperature. Then, Ni0.5Cu0.5Fe2O4 magnetic nanoparticles were applied as a green, convenient, effective and reusable catalyst for the one-pot three-component synthesis of tetrahydrobenzo[b]pyrans in good to excellent yields. It should be noted, the nanocatalyst is separated by a magnet was used several times and it was as efficient as ever.
