低聚物2 4 6。6a分别由四氟乙烯、八氟环戊烯和六氟环丁烯衍生，用汞齐钠脱氟后转化为相应的二烯7-9。还描述了使用四（二甲氨基）乙烯（TDAE）的替代路线，并形成TDAE的氟化物盐。二烯7对紫外的吸收具有很低的消光系数。
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.
