Access to unsymmetrical secondary dihetarylamines through the Cu(OAc)2/2-acetylcyclohexanone catalyzed cross-coupling of s-tetrazinylamines with iodofurazans has been developed. The reaction displays good functional group tolerance, involving nitro, azido, and azo groups, which are critical for the construction of energetic materials. Both 3,6-disubstituted and annelated s-tetrazines react readily

The firstgeneral synthetic route has been developed for the convenient preparation of iodofurazans. The approach was accomplished by one-pot diazotization-iodation reaction of appropriate aminofurazans. A combination of sodium nitrite and iodine in organic solvent under anhydrous conditions as the reaction conditions allowed to solve problem in iodofurazans preparation. The investigation of the substituent's

performance biocidalagents. Among them, compound 2 can be synthesized in one step with a high yield of 68%. Compound 3 exhibit positive oxygen balances and superior detonation performance, with a detonation velocity of 6668 m s−1, which is the highest among all reported organic energetic biocidal materials. In order to improve the comprehensive performance of bactericidal materials, compounds 5 and 6
环境和气候的变化导致生物危害频发,使人类面临生物安全的挑战。全球范围内对新型高效杀菌材料的研究持续增长。呋喃嗪首次被引入含碘杀菌材料领域。通过简单的步骤合成了四种含碘呋咱化合物。所有制备的化合物均通过红外、核磁共振波谱和元素分析进行了充分表征。所有化合物都具有高爆速(>5000 ms -1)和碘含量(>50%),表明其作为高性能杀菌剂的潜在用途。其中化合物2可一步合成,收率高达68%。化合物3具有正氧平衡和优异的爆轰性能,爆速为6668 ms -1,是所有已报道的有机含能杀菌材料中最高的。为了提高杀菌材料的综合性能,通过桥联1,2,4-三唑合成了化合物5和6 。这两种化合物不仅具有较高的爆速和爆压,而且还具有良好的热稳定性(≥235℃)和高的碘含量(≥58.5%)。这项研究为未来设计和合成高能杀菌化合物提供了一个有前景的策略。
