Solvolysis of two optically-active homoallenic tosylates, leads to cyclic products (cyclopropyl ketones and methylenecyclobutanols) with inversion of configuration at the carbon bearing the leaving group, without loss of optical activity. A kinetic study has allowed a separation of the rate in kΔ and ks terms. It is found that kΔ is always greater than ks, particularly when the allene group is methyl-substituted
两种旋光性高芳烯基甲苯磺酸盐的溶剂化产生环状产物(环丙基酮和亚甲基环丁醇),该环状产物在带有离去基团的碳上具有构型反转,而不会损失光学活性。动力学研究允许以kΔ和k s为单位来分离速率。发现kΔ总是大于k s,特别是当烯丙基被甲基取代时。
