FIELD: chemistry.
SUBSTANCE: present invention relates to a method of producing polyfluoroallyl esters containing halogen atoms different from fluorine - valuable monomers for synthesis of various copolymers used as sealing materials in various engineering fields, for example aviation engineering and electronics industry. The method involves reaction of acid fluorides of polyfluorohalogen carboxylic acids with a group I metal fluoride in aprotic solvent and then reacting the formed metal alkoxide with perfluoroallyl fluorosulphate. The process takes place in the presence of a quaternary phosphon salt of general formula: 
, where X - CI, Br, I n=1-10, in amount of 0.01-0.05 mole per mole of metal fluoride.
EFFECT: method enables to obtain desired products with high output.
