Compared with t-BuOK-t-BuOH, syn eliminations from trans-1-bromo-2-chlorocycloalkanes (C4-C8) induced by NaNH2-NaO-t-Bu in THF are rapid, exhibit greater propensity for dehydrechlorination and show little sensitivity to ring size of the dihalocycloalkane.
与t-BuOK-t-BuOH相比,NaNH 2 -NaO-t-Bu在THF中诱导的反式1-溴-2-氯环烷烃(C 4 -C 8)的同构消除速度快,表现出更大的脱水氯化倾向,并且对二卤代环烷的环尺寸几乎不敏感。
