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.
