In this work, the treatment of 3,6,7‐triamino‐[1,2,4]triazolo[4,3‐b][1,2,4]triazole (TATOT)^[1] with sulfuric acid and sodium nitrite results in elimination of the N‐amine and the formation of the new energetic anion 3,6‐dinitro‐[1,2,4]triazolo[4,3‐b][1,2,4]triazolate (DNTT) via nitro‐Sandmeyer chemistry. This new energetic anion is available in a convenient and inexpensive three‐step process from inexpensive commercial starting materials. Several nitrogen rich salts of this material have been prepared and their chemical (infrared, Raman, NMR, single‐crystal X‐ray) and energetic (impact, friction, thermal) properties determined. As a rule, this class of energetic salts are insensitive energetic materials.

3,6-二硝基-[1,2,4]三唑并[4,3-b] [1,2,4]三唑盐阴离子的盐的合成和表征：可从经济前体获得的不敏感的高能材料

在这项工作中，用硫酸和亚硝酸钠处理3,6,7-三氨基-[1,2,4]三唑[4,3-b] [1,2,4]三唑（TATOT）^[1]导致消除N胺并通过硝基形成新的高能阴离子3,6-二硝基-[1,2,4]三唑[4,3-b] [1,2,4]三唑酸酯（DNTT）桑德迈尔化学。这种新的高能阴离子可通过廉价的商业原料，通过便捷且廉价的三步法获得。已经制备了这种材料的几种富氮盐，并确定了它们的化学（红外，拉曼，NMR，单晶X射线）和高能（冲击，摩擦，热）性质。通常，这类高能盐是不敏感的高能材料。
