  十氟环己烯的光化学异构化衍生物及其反应

  摘要：

  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）
