这里描述了 5-hydrazino-3-nitro-1,2,4-triazole ( HNT ) 的首次合成,作为游离碱,来自 5-bromo-3-nitro-1,2,4-triazole ( BNT )分三步。发现HNT代表了一个有价值的平台,用于开发功能强大且热稳定的高能化合物。通过阳离子和阴离子盐的合成证明了其特定的两性特性。测量了化合物3-4、6-8和12-15的密度和生成焓,并使用这些实验数据计算了各自的P CJ和D CJ 。在源自HNT的化合物中,高氯酸盐7表现出卓越的性能,具有1.95 g cm -3的高密度和出色的爆速(9505 ms -1)和压力(419 GPa),从而在性能上超过了RDX 。稠合三唑并[4,3- b ]三唑4由于其低灵敏度、高热稳定性( T dec 313 °C)和超过HNS的综合性能数据,也显示出作为新型潜在耐热炸药的可能性。所有化合物均通过1 H
Diphenylmethyl and tetrahydropyranyl protecting groups in the synthesis of 3-substituted 5-amino- and 5-hydrazino-1,2,4-triazoles
摘要:
The use of hydrazine as reagent in nucleophilic substitution and reduction in the 1,2,4-triazole series in combination with introduction of labile protecting groups makes it possible to synthesize 5-hydrazino3-vitro-1H-1,2,4-triazole and 3-chloro-5-hydrazino-lH-1,2,4-triazol-5-ylhydrazine which were difficultly accessible previously, as well as to extend the series of 3-substituted 5-amino-1H-1,2,4-triazoles.
