実験手順
6.8 g of trifluoromethanesulfonic anhydride was added dropwise to 5.0 g of 2,2,3,3,4,4,5,5,5-nonafluoropentanol at 0° C., and the mixture was stirred at room temperature for 5 hours and at 100° C. for 3 hours. Thereafter, the reaction mixture was poured to ice water and then extracted with methyl tert-butyl ether. The organic layer was washed successively with water, aqueous saturated sodium hydrogen carbonate and aqueous saturated sodium chloride, dried over anhydrous magnesium sulfate, and then concentrated under reduced pressure to obtain 4.7 g of 2,2,3,3,4,4,5,5,5-nonafluoropentyl trifluoromethanesulfonate.
