PROCESS FOR PREPARING DECAFLUOROCYCLOHEXENE

Disclosed herein is a process of preparing decafluorocyclohexene 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 1-50 wt % of cobalt difluoride with 50-99 wt % of other metal fluoride selected from calcium fluoride, magnesium fluoride, aluminum fluoride, sodium fluoride and potassium fluoride. The mixture reacts with fluorine gas at 200-400° C.

Electrochemical fluorination of unsaturated sulfides and sulfones

Electrochemical fluorination of some unsaturated sulfides and sulfones and their reactions with anhydrous HF were studied.

Skeletal Rearrangements during the Fluorination of C6-Hydrocarbons over Cobalt(III) Trifluoride

Perfluorination of hexane, 2-methylpentane, 3-methylpentane, 2,2-dimethylbutane, 2,3-dimethylbutane, methylcyclopentane and cyclohexane over cobalt(III) trifluoride gave, in each case except perhaps cyclohexane, a mixture of linear, branched and cyclic C6-fluorocarbons: the degree of skeletal rearrangement (excluding cyclohexane) varied from ca. 7percent (methylcyclopentane) to 96percent (2,2-dimethylbutane).A carbocation mechanism, which does not proceed to equilibrium, is suggested.
