A solution of 213.6 g (0.571 mol) of potassium perfluoro-2,3-dimethyl-2-butanolate in 250 ml of dry diethyl ether was added dropwise with stirring at a temperature of 25° C. to a solution of 62 g (0.571 mol) of α-fluoroacryloyl chloride (obtained according to Example 4) in 100 ml of dry diethyl ether in the course of 1 hour, and a colorless solid precipitated. The reaction mixture was stirred at a temperature of 25° C. for a further hour, and the solid was filtered off. The filtrate had added to it 0.01 g of hydroquinone monomethyl ether and was then distilled under reduced pressure. 167 g (72 percent of theory) of perfluoro-2,3-dimethyl-2-butyl α-fluoroacrylate having a boiling point of 43° C. (under 20 mbar) were obtained.
