A novel oxidation system SO2F2/H2O2/base was investigated for the oxidation of sulfides and the corresponding sulfones were smoothly generated in good to excellent yields. The effects of base and solvent on oxidation were studied. The results showed that this oxidation system is tolerable to a variety of functional groups. A distinct advantage of this method is that by-products resulting from the use of the oxidation system are all water-soluble inorganic compounds, and can be conveniently removed after work-up process, therefore purification of the products is greatly simplified.

Key words: sulfuryl fluoride, hydrogen peroxide, oxidation, sulfides, sulfones
