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。

good yields and excellent purity. This method was also suitable for preparing the first bis-thiocarbamoyl chlorides from N,N'-bis(trimethylsilyl)-diamines. Bis-thiocarbamoyl chlorides are useful synthetic intermediates.

Reductive silylation of the uranyl dication with 1,4-bis(trimethylsilyl)dihydropyrazine, or “Mashima's reagent”, is detailed. The reagent simultaneously delivers silylium ions and electrons to multiple uranyl complexes, i.e. a pyridine dipyrrolide uranyl complex and a common uranyl-containing starting material, UO2Cl2(OPPh3)2. This reaction results in quantitative activation of thermodynamically robust
详细介绍了用 1,4-双(三甲基甲硅烷基)二氢吡嗪或“Mashima 试剂”对铀酰二阳离子进行还原甲硅烷基化。该试剂同时将甲硅烷离子和电子传递给多个铀酰配合物,即吡啶二吡咯化合物铀酰配合物和常见的含铀酰起始材料UO 2 Cl 2 (OPPh 3 ) 2。该反应导致热力学稳健的 U O 键的定量活化。用 Mashima 的试剂对环境持久的actinyl 物种进行还原功能化被视为核废料修复的有前景的解决方案。
