Procedure
48.0 g (90 mmol) of monodecyl mono(3,3,4,4,5,5,6,6,6-nonafluorohexyl)maleate, 10.4 g (99 mmol) of sodium hydrogen sulfite and 50 mL of water/ethanol (1/1 v/v) were mixed together and heated under reflux for 5 hr. Thereafter, ethyl acetate was added, and the organic phase was washed with a saturated aqueous sodium chloride solution. The resultant organic layer was collected, and the organic solvent was distilled off in vacuum. Recrystallization from acetonitrile was performed, thereby obtaining 12.5 g (yield: 22%) of desired compound as a colorless transparent solid.
