The alpha-fluoroacryloyl fluoride precursor of alpha-fluoroacrylic acid esters can arise from an allylic transposition of trifluoroallylic alcohol of which two methods of preparation are presented. In the first, dehydrofluoration of the alcohol CF3CFHCH(3)OH (4) is used. This alcohol is generated from the ester CF3CFHCOOC2H5 (3). In the second, dehalogenation of the alcohol CF3CFBrCH2OH (10) by zinc is used. The latter is formed by the selective reduction of the ester CF(3)CFBrCOOC2H(5) (9).
