研究了7-氧杂苯并降冰片二烯在钌系引发剂引发的易位共聚反应中的反应活性。它的反应性与异戊烯一样，比环戊烯高约8倍，比苯并降冰片二烯高至少19倍。讨论了邻近7位氧原子在促进[2 + 2]环加成反应过渡态中的作用。(C)2003 Elsevier B. V.保留所有权利。
The comparative reactivity of 7-oxa-benzonorbornadiene in metathesis copolymerization reactions using Ru-based initiators has been investigated. It is as reactive as norbornene, about 8 times more reactive than cyclopentene, and at least 19 times more reactive than benzonorbornadiene. The role of the proximate 7-oxygen atom in facilitating the transition state of the [2 + 2] cycloaddition step is discussed. (C) 2003 Elsevier B.V. All rights reserved.
