Abstract
In this paper, an oxovanadium(V) complex, prepared with a tridentate ONO Schiff base by reacting nicotinic hydrazide with 3-methoxysalicylaldehyde, was immobilized on the surface of the silica-coated magnetite nanoparticles. After successful preparation and complete characterization (FT–IR, SEM, XRD, TEM, VSM, EDX, and ICP), the catalytic activity of the magnetic organic–inorganic nanocomposite was explored for the green oxidation reaction of different kinds of aryl and alkyl sulfides employing hydrogen peroxide and methanol under reflux conditions. Significant features such as simple work-up, fast reaction, higher product yield, and reusability of the catalyst enhance the efficiency of this catalytic procedure economically and environmentally.
