This work shows the ability of a readily‐available oxidizer to achieve the selective oxidation of 3,5‐diamino‐1,2,4‐triazole (DAT) to 3‐amino‐5‐nitro‐1,2,4‐triazole (ANTA) in high yields. This strategy reduces the synthesis of this important energetic material and synthon down to a single step. Analysis was conducted on the product and confirmed that the product was indeed ANTA. The yield, safety, and economics of this process are all superior to the current state‐of‐the‐art two‐step multi‐pot procedure.

不敏感的含能材料3-氨基5-硝基-1,2,4-三唑（ANTA）的改进合成

这项工作表明了一种现成的氧化剂能够将3,5-二氨基-1,2,4-三唑（DAT）选择性氧化为3-氨基-5-硝基-1,2,4-三唑（ ANTA）。该策略将这种重要的高能材料和合成子的合成降低到一个步骤。对产品进行了分析，并确认该产品确实是ANTA。该方法的产率，安全性和经济性均优于当前最新的两步多罐法。
