最后一种环状乙烯基阳离子：环戊烯-13-溴的简单溶剂分解在室温下有效地生成了高度应变的环戊基-1-烯基阳离子(见图)。这种独特的单分子解离是由芳基-13-溴基的高离核性造成的。
Last of the cyclic vinyl cations: The simple solvolysis of cyclopent-1-enyl-13-bromane efficiently generates the highly strained cyclopent-1-enyl cation at room temperature (see scheme). The very high nucleofugality of the aryl-13-bromanyl groups are responsible for this unique unimolecular dissociation.
