摘要：Abstract: In the present study, copper complex supported on surface-modified Fe3O4/SiO2 nanoparticles (Fe3O4@SiO2–Glycerole–Cu(II)) was successfully fabricated and characterized by fourier transform infrared spectroscopy (FT-IR), thermal gravimetric analysis (TGA), scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray mapping, energy-dispersive X-ray spectroscopy (EDS), inductively coupled plasma optical emission spectroscopy (ICP-OES), N2 adsorption and desorption (BET) and Vibrating Sample Magnetometer (VSM) techniques. This magnetic nanocatalyst utilized as an effective catalyst for the C–S and C–O cross-coupling reactions of aryl halides with thiourea and phenol. The catalyst could be quickly and completely recovered using an external magnetic field and reused for six reaction cycles without significant change in catalytic activity. Graphic Abstract: A green and novel Fe3O4@SiO2–Glycerole–Cu(II) catalyst successfully was prepared and characterized. This catalyst can be used for the C– and C–O cross coupling reactions. Fe3O4@SiO2–Glycerole–Cu(II) could be recovered easily and reused many times without important decrease in efficiency. ? 2019, Springer Science+Business Media, LLC, part of Springer Nature.
