-butene react with pentafluoropyridine in the presence of caesium fluoride to give perfluorocycloalkylpyridines. Di-and tri-substituted pyridines are obtained only from perfluorocyclohexene, and perfluorocycloalkyl derivatives are isolated only from perfluorocyclohexene on reaction of these cyclic olefins with tetrafluoropyridazine. Fluorideion induces dimerisation of perfluorocyclo-pentene and -hexene whereas

Perfluoro-(methylenecyclopentane) and -(1-methylcyclopentene), together with some higher-boiling compounds, have been obtained by the u.v.-irradiation of decafluorocyclohexene. Perfluoro-(methylenecyclopentane) underwent addition of chlorine and isomerisation to perfluoro-(1-methylcyclopentene), catalysed by fluoride ion; on treatment with sodium borohydride in bis-(2-methoxyethyl) ether it gave 1H-hexaf

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 observed in the balance between exo-
