Procedure

12.56 grams (0.03 mol) of 5-iodooctafluoro-3-oxapentanesulfonyl fluoride (Synquest) was taken in a flask in water and excess amount of KOH (0.06 mol, 3.31 grams) was added and the resulting mixture was heated under stirring at 80° C. for six hours. To this reaction mixture (after cooling to room temperature) was added 1:2 v/v THF/water solution of triphenyl sulfonium bromide (0.03 mol, 10.14 grams) dropwise over a period of one hour with stirring. After the addition, the reaction mixture was further stirred for additional 3 hours at room temperature. Upon completion, the target compound triphenylsulfonium 5-iodooctafluoro-3-oxapentafluoro sulfonate was extracted using methylene chloride. It was washed at least three times with DI water. Methylene chloride was evaporated to get a pale yellow liquid. It was redissolved in methylene chloride and precipitated into hexanes. Yield was 82%. Melting point (capillary) 110-112° C.
