PROCESS FOR PREPARING OCTAFLUOROCYCLOHEXADIENE

Disclosed herein is a process of preparing octafluorocyclohexadiene using hexafluorobenzene as a raw material. The hexafluorobenzene reacts with an activated fluorinating agent at 60-200° C. in an inert gas atmosphere. The activated fluorinating agent is prepared by mixing 1-10 wt % of cobalt difluoride with 90-99 wt % of other metal fluoride selected from the group of calcium fluoride, magnesium fluoride, aluminum fluoride, sodium fluoride and potassium fluoride. The mixture reacts with fluorine gas at 200-400° C.

Thermal and UV-induced isomerisation of fluorinated hexatrienes

Irradiation of octafluoro-1,3,5-hexatriene (I) in the gas phase with a high-pressure mercury lamp gave a mixture of octafluoro-2-vinyl-cyclobutene (III) and octafluorobicyclohex-2-ene (V).The analogous photolysis of hexatriene I in the liquid phase led to an equilibrium mixture of the starting compound I (cis-isomer) and the trans-isomer II, respectively.Photolysis of 2,3,4,5-tetrafluro-1,3,5-hexatriene (VI) gave a mixture of cis- and trans-isomers, both in the vapour and liquid phases.Thermal reaction of hexatriene I gave octafluoro-1,3-cyclohexadiene (IV) as the sole product.
