exceedingly versatile 2-nitroperchlorobutadiene (1) gave structurally interesting and physiologically promising nitro-enamines, -imines, -amidines, and hydrazines as well as ring closure reaction products, e. g. pyrimidines and pyrazoles. Most of these reactions turned out to be highly selective with good to very good yields. The structure of the pyrazole precursor (E,E)-1-(benzotriazol-1-yl)-4,4-dichloro-3-
衍生自极其通用的 2-硝基全氯丁二烯 (1) 的各种氨基、二氨基、氨基硫代或苯并三唑并化合物提供了结构有趣且生理学上有前景的硝基烯胺、-亚胺、-脒和肼以及闭环反应产物,例如嘧啶和吡唑类。大多数这些反应被证明是高度选择性的,产率非常好。吡唑前体(E,E)-1-(benzotriazol-1-yl)-4,4-dichloro-3-(4-ethoxyphenylamino)-1-(4-ethoxyphenylimino)-2-nitrobut-2-的结构单晶 X 射线衍射分析证实了 ene (30) 由于其特殊的取代模式。多卤化硝基丁二烯的图形摘要化学,第 9 部分:来自 2-Nitroperchlorobuta-1,3-diene 的无环和杂环硝基烯胺和硝基亚胺
