A method is described for the synthesis of 2-fluoropropenoic acid esters, amides, and nitrile from the corresponding derivatives of 2-fluoro-3-(4-toluenesulfonyloxy)propanoic acid by heating with potassium phtalimide in vacuo.The free acid Ia and its chloride have also been synthetized.The reactivity of esters and nitrile of acid Ia has been verified by the Michael addition of diethyl acetamidomalonate to these compounds.

Process for making an acrylic monomer
The invention relates to a novel process for making phenyl fluoroacrylate monomer. The monomer is obtained by reaction of a fluoroacrylic salt with an halogenating agent, followed by condensation of the fluoroacryloyl halogenide with phenol and recovery of the phenyl fluoroacrylate. The obtained monomer is applicable to the manufacture of transparent polymers of high thermal stability.
