  五氧化二氮（N 2 O 5）将氮丙啶开环硝化制备硝酸硝胺

  摘要：

  在环境温度下，在氯化溶剂中用N 2 O 5处理13个在环氮上带有各种取代基的氮丙啶，并通过类似于所建立的新型开环硝化反应，形成1，2-硝胺硝酸盐产物。相应的氧杂环（环氧化物）。各种类型的氮丙啶进行了反应（N-烷基，N-（硝基芳基），N-酰基和N-亚氨基），尽管在一种情况下，收率很高（70-82％） N-（烷基羰基）氮丙啶竞争的脱酰反应导致产率降低。另外，带有氮丙啶的基团能够通过N 2 O 5释放硝酸 由于竞争性反应（主要是聚合/低聚），因此（即具有O = H，N = H或未取代的芳基的化合物）大大降低了硝酸硝胺的收率。
