8–14 by a retro-Diels-Alder reaction under flash thermolytic conditions. The primary enamines 1–4 have been identified (IR, 1H and 13C NMR) in a pure state at −80°; at the same temperature, the enamines 5–7, less stable, are already accompanied by their tautomeric imines 33 or 34. When warmed up to room temperature, the enamines 1–7 lead, following to their substitution, either to nitrogen heterocycles
乙烯胺1和其甲基衍生物2 - 7已经从加合物合成8 - 14通过快速热分解的条件下,逆狄尔斯-阿尔德反应。主烯胺1 - 4已得到鉴定(IR,1 H和13 C NMR)在-80℃纯态; 在相同温度下,烯胺5 - 7,稳定的少,已经伴随着其互变异构亚胺33或34。升温至室温时,烯胺1 – 7铅,以下对它们的取代,无论是含氮杂环(30,42)或无环的azadienes(35 - 37,39,40)。
