Catalytic Oxidation of Aryl Alkyl Sulfides Using Immobilized Vanadyl Ions within Nanoreactors of Al-MCM-41

摘要

VOSO4 immobilized within nanoreactors of Al-MCM-41(VO2+/Al-MCM-41) was synthesized and characterized by X-rav digfraction,Fourier transform infrared spectroscopy,nitrogen adsorption-desorption,and chemical analysis techniques.The prepared VO2+/Al-MCM-41 successfully catalyzes the oxidation of aryl alkyl sulfides and up to 99% conversion and 90% selectivity for the corresponding sulfoxidas were obtained with H2O2 as oxidant in acetonitrile at room temperature in 30 min.
