Reaction of octafluorotoluene and perfluoro-m-xylene with tetrafluoroethylene in the presence of SbF5 yielded perfluorinated propyl-and 1,3-dipropylbenzene, and propyltoluene. The perfluoropropyl group of these compounds under the action of SbF5 at 200°C is transformed into perfluoroisopropyl or trifluoromethyl group. Polyfluoroalkylbenzenes in SbF5 medium undergo fluorinationb to afford perfluoro1-alkylcyclohexenes.

Unlike perfluorocyclobutene, perfluorocyclo-pentene and -hexene do not form oligomers with pyridine.A range of oligomers is obtained from mixtures of perfluorocycloalkenes in reactions initiated by caesium fluoride.Products are also obtained from perfluorocycloalkenes with perfluoropropene and between perfluorocyclobutene and perfluorobut-2-ene.A variation is obseved in the balance between exo- and endo-isomers of perfluorocycloalkene oligomers.It is concluded that conformational interactions dominate the position of equilibrium, exept with four-membered rings, where angle strain is also important.
