Abstract
Fluoride adds to hexafluorobut-2-yne to give a perfluorovinyl and a perfluoro-alkadienyl carbanion, which can displace fluoride ion from perfluoro-aromatic or -heterocyclic compounds to give alkenyl- and alkadienyl-aromatics or -heterocyclics Ar[C(CF3) : C(CF3)]nF (n= 1 or 2); nucleophilic attack on a perfluoroalkenyl aromatic can displace vinylic or aryl fluorine.Keywords
