| Abstract: | Magnetic core–shell titanium dioxide nanoparticles (Fe3O4@SiO2@TiO2) were applied for the efficient preparation of 1,2,4,5‐tetrasubstituted imidazole derivatives by the one‐pot multi‐component condensation of benzil with aldehydes, primary amines and ammonium acetate under solvent‐free conditions. The catalyst was synthesized and studied using several techniques including X‐ray diffraction, transmission electron microscopy, field‐emission scanning electron microscopy and energy‐dispersive X‐ray spectroscopy.
