ABSTRACT OF THE DISCLOSURE 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, manganese, silver or the like at temperatures generaily must 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.
