Reactions involving perfluoro-2-iodopropane and 1,1-difluoroethene, give telomers (1) and these telomer iodides are coupled to give [(CF3)2CF(CH2CF2)n-]2 (2). Fluorodeiodination gives a series of compounds (CF3)2CF(CH2CF2)nF (3). Lewis acid-induced eliminations from these systems is very effective using SbF5 and cyclisations can also be induced by this methodology. A series of conjugated polymers is obtained by exposure of films of PVC, PVDF, and polytrifluoroethene to SbF5 vapour.
