Perfluorinated polycyclic hydrocarbons may be produced in high yield by a three-stage process comprising contacting a cyclic hydrocarbon such as an alkyladamantane with a fluoride of silver, manganese, sulfur or the like under varying reaction conditions, generally in the liquid state, to provide a partially fluorinated cyclic hydrocarbon. This fluorination is followed by a second stage vapor phase reaction with a fluoride of cobalt or the like at temperatures generally just above the boiling point of the material to yield highly fluorinated cyclic compounds, followed by a third stage reaction with the same reagent at substantially higher temperatures to provide the desired perfluorinated material. Alternatively, the partially fluorinated material for use in the second stage may be derived from known sources, using any known partially fluorinated cyclic hydrocarbon. In a further embodiment, a fluidized bed reactor may be substituted for the second and third vapor phase stages described above.
