Reaction Steps
To a solution of 55.5 g (0.2 mole) of 2,3-difluoropropionic acid-2,2,3,4,4,4-hexafluorobutylester and a spatula tipful of hydroquinone in 550 ml of dry diethyl ether there was added dropwise at -10° C. a solution of 23 g (0.19 mole) of 1,5-diazabicyclo[4.3.0]non-5-ene in 140 ml of dry diethyl ether. The solvent was then distilled off in vacuo in the cold and the residue remaining was fractionated. In this way, 23 g of 2,2,3,4,4,4-hexafluorobutyl α-fluoroacrylate were obtained having a boiling point of 53° to 54° C. at 20 mbar and a purity of 98%.
