Procedure
A solution of 34 g of (4,4,5,5,5-pentafluoropentyl)-vinyl sulfide in 74 ml of glacial acetic acid is mixed drop by drop with 59 ml of 30% hydrogen peroxide in such a way that the reaction temperature does not exceed 70° C. Then, it is stirred for one hour at a bath temperature of 70° C. Then, it is added to water, extracted three times with ethyl acetate, washed with sodium thiosulfate, water and common salt solution, dried on sodium sulfate, concentrated by evaporation in a vacuum and chromatographed on silica gel with hexane/ethyl acetate. 12.3 g of (4,4,5,5,5-pentafluoropentyl)-vinyl sulfone is obtained as an oil.
