摘要：

Reactions involving perfluoro-2-iodopropane and 1,1-difluoroethene, give telomers (1) and these telomer iodides are coupled to give [(CF3)(2)CF(CH2CF2)(n)-](2) (2). Fluorodeiodination gives a series of compounds (CF3)(2)CF(CH2CF2)(n)F (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.
