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.
