Highly fluorinated aromatic compounds and their derivatives will react with carbanions produced from fluorinated olefins and fluoride ion, with the formation of polyfluoroalkyl derivatives, in a process which is the nucleophilic equivalent of the Friedel-Crafts reaction in hydrocarbon chemistry. Reaction occurs between hexafluoropropene and pentafluoropyridine, pentafluoronitrobenzene, and other activated

Synthesis of perfluoropolyisopropylpyridines by fluoride-ion-initiated reactions of hexafluoropropene with pentafluoropyridine at atmospheric pressure is described. Trisubstitution gives a mixture of perfluoro-2,4,5- and 2,4,6-tri-isopropylpyridines; the ratio of these varies with reaction temperature but the 2,4,5-isomer can be obtained as the principal product. The 2,4,5-isomer is rearranged to the
