Vanadium pentafluoride reacts with polyfluorinated and polychlorinated olefins, alkadienes, cycloalkenes and cyclodienes in CFCl3 or without a solvent at -25 deg C to 100 deg C, forming products of addition of two fluorine atoms across the C=C bond.

Polyfluorinated 1,3- and 1,4-cyclohexadienes are fluorinated by vanadium fluoride at -25 to 25 deg C.The olefinic fragments of perfluoro-1,3- and perfluoro-1,4-cyclohexadienes are close to each other in reactivity.Under the influence of vanadium pentafluoride the fluorine atoms add to 1-R-heptafluoro-1,4-cyclohexadienes preferentially at the multiple bond containing the less electron-withdrawing substituent.At -80 to 20 deg C antimony pentafluoride leads to isomerization of the polyfluorinated derivatives of cyclohexadiene.

Polyfluorinated cycloalkanes are fluorinated by vanadium pentafluoride at 25-60 deg C.Conjugation between the C=C bond of the cycloalkene and the aromatic ring facilitates the reaction, whereas the reactivity of the unconjugated olefin fragment is lower than or is equal to that of the aromatic ring.The antimony pentafluoride fluorinates polyhalogenocyclohexenes at 150 deg C, while niobium pentafluoride does not exhibit fluorinating characteristics under these conditions.

The treatment of C6F5R (R=CH3, CH2F, CHF2) compounds with vanadium pentafluoride at -25 to -30 deg C leads to a 1-R-heptafluoro-1,4-cyclohexadienes, 1-R-nonafluorocyclohexenes, and products form fluorination of the side chain.Fluorination of the anisole derivatives C6F5OCH3 and C6F5OCHF2 only takes place in the aromatic ring.
