Resumen:
In this research, a new and selective procedure for the oxidation of sulfides, aromatics and aliphatics, to sulfoxides and sulfones, with 35 % aqueous H2O2 and acetonitrile as solvent. Catalytic amount of new Keggin heteropolyacid H5PMo11Al 0.5V0.5O40 were used. The yields were excellent and all reagents are cheap and easily available. The reaction for preparation of sulfoxides was carried out at room temperature and short times. The oxidation to sulfones proceeded at 40°C in also excellent yields.
