[reaction in text] Treatment of (2-azaallyl)stannanes (i) with 2.2 equiv of allylmagnesium bromide afforded good yields of N,N-bis(3-butenyl)amines derivatives (ii), which were subjected to ring-closing metathesis to afford 2,3,6,7-tetrahydroazepines (iii). Thus, (2-azaallyl)stannanes are the synthetic equivalents of amine alpha,alpha'-dications.
[文本中的反应] 用2.2当量的烯丙基溴化镁处理(2-氮杂烯丙基)锡烷(i)，可高产率地得到N,N-双(3-丁烯基)胺衍生物(ii)，将其进行闭环复分解反应得到2,3,6,7-四氢氮杂卓(iii)。因此，(2-氮杂烯丙基)锡烷是胺α,α'-双阳离子的合成等效物。
