FIELD: chemistry.
SUBSTANCE: invention relates to method for fluorinating halogenated olefines, involving reaction of elementary fluorine in presence of anhydrous HF with halogenated olefine of formula CXR1=CYR2 (I), where: R1 is selected from group consisting of F, Cl, Br, I, Rf1, ORf1; R2 is selected from group consisting of H, F, Cl, Br, I, Rf2, ORf2; X is selected from group consisting of H, F, Cl, Br, I; Y is selected from group consisting of H, F, Cl, Br, I; and Rf1 and Rf2, identical or different from each other, are independently selected from linear or branched C1-C20 fluoroalkyl or C1-C20 fluoroxyalkyl containing one or more oxygen atom in chain; and Rf1 and Rf2 can be contained in structure of fluorinated cycloalkyl, where anhydrous HF is used as only reaction medium.
EFFECT: technical result is high output and selectivity in product obtained by bonding of fluorine to carbon-carbon double bond, without need in use of complex equipment.
