Resumen en español En esta investigación, se ha encontrado un nuevo y selectivo procedimiento de oxidación de sulfuros aromáticos y alifáticos, en sulfóxidos y sulfonas, empleando 35% H2O2 y acetonitrilo como solvente de reacción. Esta oxidación selectiva se realiza en presencia de cantidades catalíticas de un nuevo heteropoliácido, H5PMo11Al0.5V0.5O40, con estructura tipo Keggin. Los rendimientos fueron excelentes y todos los reactivos son baratos y de fácil acceso. La reacción (mas) para la preparación de sulfóxidos fue llevada a cabo a temperatura ambiente y a cortos tiempos. La oxidación a sulfotas procede a 40 C dando también excelentes rendimientos Resumen en inglés 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 H5PMo11Al0.5V0.5O40 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
