A cyclohexenyl cation equilibria which effectively "pits" alkyl groups against one another yields equilibrium constants in the hyperconjugative order direction; however the size of the free energy differences are only about 60% of those observed for the identical cyclopentenyl cation member. The rate of the equilibrium reaction was studied, as was the rate of several aberrant ion–ion rearrangements
一种环己烯基阳离子平衡,它有效地使烷基相互“坑”,在超共轭顺序方向上产生平衡常数;然而,自由能差异的大小仅为相同环戊烯基阳离子成员所观察到的那些的大约 60%。研究了平衡反应的速率,以及几种异常离子 - 离子重排的速率,其中一个是叔丁基取代的离子导致了特殊问题。不幸的是,结果似乎与空间或超共轭论点一致。
