Some new chemistry of perfluoro-t-butylsilver

Perfluoro-t-butylsilver, prepared by the reaction of silver fluoride with perfluoroisobutene, has been used to prepare new perfluoro-t-butyl derivatives in good yield.

REACTIONS INVOLVING FLUORIDE ION. PART 34. STABLE PERFLUORINATED CARBANIONS

A remarkable series of perfluoroalkyl anions, generated by reaction of caesium fluoride with various perfluorinated alkenes have been observed by (19)F and (13)C n.m.r. spectroscopy.Trapping experiments are described and threshold temperatures are established for the onset of fluoride ion exchange.The effects of counter ions are compared and (Me2N)3S+ (TAS) salts are more readily produced than Cs+ salts, but exchange of fluoride ion with fluorinated alkenes occurs more readily with TAS salts.Ph4P+ and Bu4N+ salts could not be obtained.Competition experiments for CsF between various perfluoroalkenes has established orders of carbanion stability.

Direct Observation of Simple Fluorinated Carbanions

Simple perfluorinated carbanions are generated and observed by (19)F and (13)C n.m.r. spectroscopy; curious low-field shifts are observed for sites adjacent to the charged centres.
