| Abstract: | Fluorine-containing alkyl 2-cyano-3-oxocarboxylates were synthesized for the first time by the reaction of ethyl cyanoacetate with fluorine-substituted carboxylic acid halides or alkyl carboxylates. The reactions with hydrazine hydrate, phenylhydrazine, ando-phenylenediamine give hydrazinium (ammonium) enolates or products of acid decomposition. Translated fromIzvestiya Akademii Nauk.
