Abstract

La presente invención se refiere al uso de gel de sílice funcionalizado con 3-mercaptopropilo como agente reductor para la reducción catalítica de compuestos orgánicos que incluyen un grupo funcional sulfóxido a compuestos tipo sulfuro en presencia de un catalizador de molibdeno (VI), en un disolvente orgánico o en un medio libre de disolventes orgánicos, bajo presión atmosférica y a una temperatura entre 130-190°C o, alternativamente, por irradiación en un horno microondas monomodo a una potencia máxima de 270 W y a una temperatura comprendida entre 130ºC y 140ºC.The present invention relates to the use of 3-mercaptopropyl-functionalized silica gel as a reducing agent for the catalytic reduction of organic compounds that include a sulfoxide functional group to sulfide-like compounds in the presence of a molybdenum (VI) catalyst, in a solvent Organic or in a medium free of organic solvents, under atmospheric pressure and at a temperature between 130-190 ° C or, alternatively, by irradiation in a single-mode microwave oven at a maximum power of 270 W and at a temperature between 130ºC and 140ºC.
