besides two normal products (of elimination and SN2 displacement), which were minor, one rearranged elimination product and a tertiary acetate. The rearranged diolefine arises from acetic acid-catalysed rearrangement of the normal elimination product, while the tertiary acetate is a Wagner substitution product arising from a syn-migration. In this context various factors controlling such migrations are discussed
除两个正常产物(消除和S N 2置换)是次要的两个正常产物(一个重排的消除产物和一个叔
乙酸酯)外,对8-
溴异
异长叶烯的乙酰化反应还会产生。重排的二烯烃源于正常消除产物的
乙酸催化的重排,而
乙酸叔是从引起的瓦格纳取代产物顺-migration。在这种情况下,讨论了控制这种迁移的各种因素,并着重指出了初始碳离子在迁移起点处的能量学作用。
