with conventional substrates (amines or alcohols). These nitrodesilylation reactions proceed cleanly and in good yield, and the scope of the reaction is illustrated by. 29 examples, some of which produce high energy compounds, notably plasticisers and an energetic polymer precursor. These reactions are therefore potentially clean nitrations for the manufacture of energetic compounds which will minimise
在这种新型的硝化方法中,使用惰性溶剂中的五氧化二氮(N 2 O 5)作为硝化剂,从而无需使用强酸作为反应介质。N 2 O 5分别在甲硅烷基胺和甲硅烷基醚中裂解杂原子-硅键,得到所需的高能基团(分别为硝胺或硝酸酯),而不会释放常规底物(胺或醇)会发生的酸。这些氮代甲硅烷基化反应清洁且收率良好,反应范围如下所示。29个实例,其中一些可以生产高能化合物,尤其是增塑剂和高能聚合物前体。因此,这些反应是潜在的清洁硝化反应,可用于生产高能化合物,这将在将来最大程度地降低这种活性对环境的影响。
