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