  Synthesis and Properties of Alkylnitramino-1,2,4,5-Tetrazines

  摘要：

  The peculiarities of the nitration reaction under acidic conditions were studied for a series of alkylamino-1,2,4,5-tetrazines. It was found that the extent of N,N'-dialkyl-1,2,4,5-tetrazine-3,6-diamine nitration was determined by the concentration of nitric acid and the selection of alkyl substituents at the exocyclic nitrogen atom. A new method was developed for the preparation of unsymmetrically substituted N,N'-dialkyl-1,2,4,5-tetrazine-3,6-diamines from N-nitro derivatives of N-alkyl-1,2,4,5-tetrazin-3-amines.

  avoids the up-to-now required oxidation step but also lower reaction times and/or temperatures compared to usual protocols. The efficiency of the reaction was highlighted by a practical synthesis of 3,6-bis(methylamino)-1,2,4,5-tetrazine using aqueous methylamine. Other primary and secondary amines were also found to give disubstitution products when reacted with 3,6-bis(methylsulfanyl)-1,2,4,5-dihydrotetrazine

  描述了直接从3,6-二取代-1,2-二氢-1,2,4,5-四嗪前体直接合成（二）烷基氨基取代的1,2,4,5-四嗪的一步法。一项比较研究表明，与常规方案相比，所描述的方法不仅避免了目前所需的氧化步骤，而且还缩短了反应时间和/或温度。通过使用甲胺水溶液实际合成3,6-双（甲基氨基）-1,2,4,5-四嗪突出了反应的效率。当与3,6-双（甲基硫烷基）-1,2,4,5-二氢四嗪反应时，还发现其他伯胺和仲胺会产生分解性产物。
