Perfluoro-(methylenecyclopentane) and -(1-methylcyclopentene), together with some higher-boiling compounds, have been obtained by the u.v.-irradiation of decafluorocyclohexene. Perfluoro-(methylenecyclopentane) underwent addition of chlorine and isomerisation to perfluoro-(1-methylcyclopentene), catalysed by fluoride ion; on treatment with sodium borohydride in bis-(2-methoxyethyl) ether it gave 1H-hexaf
全氟-(亚甲基环戊烷)和-(1-甲基环戊烯)以及一些高沸点化合物已通过十氟环己烯的紫外线照射获得。全氟-(亚甲基环戊烷)经过氯离子加氯并异构化为全氟-(1-甲基环戊烯);在双(2-甲氧基乙基)醚中用硼氢化钠处理后,得到1 H-六氟-2-甲基环戊烯,3,3,4,4-四氟-1-三氟甲基环戊烯和五个多氟烯烃作为次要组分。在丙酮中用碘化钠处理后,全氟-(亚甲基环戊烷)和-(1-甲基环戊烯)均得到六氟-1-碘-2-三氟甲基环戊烯,其与乙醚中的镁反应生成格氏试剂,再与五氟碘苯和铜青铜,得到全氟-(2,2'-二甲基双环戊-1,1'-烯基)和六氟-1-五氟苯基-2-三氟甲基环戊烯。全氟-(亚甲基环戊烷)与氯化铝在碘代甲烷中反应生成1-(氯二氟甲基)七氟环戊烯,将其在丙酮中用碘化钠处理后,得到1-(二氟碘甲基)七氟环戊烯。两种化合物都可以脱卤氟化,得到全氟-(3-亚甲基环戊烯),该全氟-(3-亚甲基环戊烯)
