The new ethylenes, with a 2-hydroperfluorocyclobutyl, 2-chlorotetrafluoro-1-cyclobutenyl or 2-chlorohexafluoro-1-cyclopentenyl group, were synthesized in good yields by the dehydration of the 1 : 1 adducts prepared by the addition of the alcohols to perfluorocyclobutene, 1, 2-di-chlorotetrafluorocyclobutene or 1, 2-dichlorohexafluorocyclopentene respectively. The dehydro-fluorination of 2-hydroperfluorocyclobutylalkylethylenes gave a mixture of perfluoro-1-cyclo-butenyl- and perfluoro-2-cyclobutenylethylene. In the mixture, the former was predominant over the latter. Some polyfluorocycloalkenylethylenes prepared polymerized in the presence of peroxide to yield transparent polymers.
通过将醇加成到全氟环丁烯上制备的 1:1 加合物脱水,以良好的收率合成了带有 2-氢全氟环丁基、2-氯四氟-1-环丁烯基或 2-氯六氟-1-环戊烯基的新乙烯。分别为1,2-二氯四氟环丁烯或1,2-二氯六氟环戊烯。 2-氢全氟环丁基烷基乙烯脱氟化氢得到全氟-1-环丁烯基乙烯和全氟-2-环丁烯基乙烯的混合物。在混合物中,前者比后者占主导地位。一些制备的多氟环烯基乙烯在过氧化物存在下聚合以产生透明聚合物。
