Charge-transfer salts containing cyclic perfluorinated anions

Perfluorobicyclopentenyl (1a) and -butenyl (2a) react with decamethylferrocene (3), to give charge-transfer salts 4 and 5, respectively; perfluorohexakis (trifluoromethyl) cyclo-pentadiene (6) forms a salt (8) containing the C5(CF3)5 anion. Crystal structures of the salts 4 and 5 have been determined; both contain centrosymmetric trans-diene radical anions.

Reactions Involving Fluoride Ion. Part 38. New Fluorinated Dienes by Defluorination

The oligomers 2, 4 and 6, 6a, derived from tetrafluoroethene, octafluorocyclopentene, and hexafluorocyclobutene respectively, are converted into their corresponding dienes 7-9 by defluorination, using sodium amalgam.An alternative route using tetrakis(dimethylamino)ethene (TDAE) is also described and forms a fluoride salt of TDAE.The diene 7 shows a remarkably low extinction coefficient for UV absorption.
