Versuchsvorschrift

Lithium chloride (985 mg, 23.24 mmol) and water (0.21 ml, 11.62 mmol) were added to a solution of diethyl 2-(6-heptenyl)-2-(4,4,5,5,6,6,7,7,7-nonafluoroheptyl)malonate (6.0 g, 11.62 mmol) in dimethyl sulfoxide (40 ml) followed by stirring for 12 hours at a temperature of 160° C. to 180° C. After the reaction was completed, water was added to the reaction mixture, which was then extracted with ethyl acetate. The organic layer was washed with water and saturated aqueous sodium chloride, and then dried over anhydrous magnesium sulfate. After distilling off the solvent, the residue was purified by silica gel column chromatography (eluent: ethyl acetate/hexane=1/40→1/30) to give ethyl 2-(4,4,5,5,6,6,7,7,7-nonafluoroheptyl)-8-nonenoate (2.3 g, Yield 44%) as a colorless oil.
