Reaction of N-Alk-N′-(trimethylsilyl)carbodiimides (Alk = Me, But) with nitrating agents (N2O5, (NO2)2SiF6) affords alkyl(nitro)cyanamides and N-alkyl-N′-nitrocarbodiimides. The product ratio depends on the reaction conditions. N-(tert-butyl)-N′-nitrocarbodiimide can be obtained in almost pure form. This compound is stable at temperatures below 10 °C. Its structure was confirmed by 1Н, 13C, and 14N
N-Alk-N'-(三甲基甲硅烷基)碳二亚胺(Alk = Me, But)与硝化剂(N2O5, (NO2)2SiF6)反应得到烷基(硝基)氰胺和N-烷基-N'-硝基碳二亚胺。产物比例取决于反应条件。N-(叔丁基)-N'-硝基碳二亚胺可以几乎纯的形式获得。该化合物在低于 10 °C 的温度下是稳定的。其结构经 1Н、13C 和 14N NMR 确证。N-(叔丁基)-N'-硝基碳二亚胺与胺的反应为制备N-烷基(芳基)-取代的N'-(叔丁基)-N″-硝基胍提供了一条新途径。
