norbornyl, endo-5,6-trimethylene-endo-8-norbornyl, and endo-5,6-trimethylene-endo-9-norbornyl cyclic tosylates has been studied. No rearrangement occurred during the reactions. The relative rates of displacement have been found to be very similar to the reactivity observed for solvolyses. Increased steric interaction by alkyl groups on the leaving group causes the displacement rate to decrease.

甲苯磺酸酯。反应期间未发生重排。已经发现相对位移速率与溶剂解所观察到的反应性非常相似。离去基团上的烷基增加的空间相互作用导致置换速率降低。
