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-

The perfluorocyclobutenederivative (8) undergoes a photochemically-induced 1,3-fluorine shift followed by keletal rearrangement; the preparation of novel spiro compounds is described.

N,N-Dimethylaniline and N-methylindole react as nucleophiles through carbon with perfluorobicyclobutylidene 1, to give the unusual products 5a and 5b; Proton Sponge reacts in an analgous way with the systems 2 and 3 but, in this case, give the novel annelated products 8 and 7.
