โœฆ Synopsis

VOSO 4 immobilized within nanoreactors of Al-MCM-41 (VO 2+ /Al-MCM-41) was synthesized and characterized by X-ray diffraction, Fourier transform infrared spectroscopy, nitrogen adsorption-desorption, and chemical analysis techniques. The prepared VO 2+ /Al-MCM-41 successfully catalyzes the oxidation of aryl alkyl sulfides and up to 99% conversion and 90% selectivity for the corresponding sulfoxides were obtained with H 2 O 2 as oxidant in acetonitrile at room temperature in 30 min.
