Vanadium (V) and tungsten (VI) oxoperoxo complexes supported on Fe3O4 magnetic nanoparticles were synthesized and characterized. These compounds are assigned as catalyst 1 (C1: Fe3O4@ Gly@r-Py@VO3) and catalyst 2 (C2: Fe3O4@ Gly@r-Py@WO3), respectively, and were found to be efficient and reusable heterogeneous catalysts for the oxidation of alcohols and sulfides using H2O2.
