Elimination of hydrogen fluoride, using antimonypentafluoride, is a useful preparative process for some fluorinated alkenes and presents a new and simple approach to conjugatedpolymers.

Reactions involving perfluoro-2-iodopropane and 1,1-difluoroethene, give telomers (1) and these telomeriodides 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
