Procedure

2,2,3,3,3-pentafluoropropanol (3.0 g) was added to a suspension of sodium hydride (1.08 g) in dry ether (50 ml) at 0° C. under an argon atmosphere. Stirred at 0° C. for 15 minutes. Perfluoro-1-butanesulphonyl fluoride (12.08 g) was slowly added. Stirred at reflux for 3 hours, cooled and carefully quenched with H2O. Extracted with ether, twice. The combined extracts were washed with saturated brine dried over MgSO4, filtered and evaporated to give 2,2,3,3,3-pentafluoropropyl-1,1,2,2,3,3,4,4,4-nonafluorobutane-1-sulphonate as an oil. Yield 7.9 g. NMR: (CDCl3) δ 4.9 (m, 2H).
