Nucleus independent chemical shift analysis was used to investigate skeleton aromaticity and the effect of the nitro-NNO-azoxy and nitro groups on ring aromaticity. Electrostatic potential, bond dissociation energy, Mulliken charges and Wiberg bond order were estimated by density functional theory to establish the molecular electron distribution and stabilities of the compounds. The nitro-NNO-azoxy group
合成了2,4-二硝基-NNO-氮氧基甲苯和2,6-二硝基-4-硝基-NNO-氮氧基甲苯作为高能化合物。通过X射线衍射,核磁共振和红外光谱研究了它们的结构和性质。讨论了硝基-NNO-氮氧基和硝基之间的差异。如使用EXPLO5预测的那样,爆震性能表明,2,4-二硝基-NNO-氮氧基甲苯的爆震速度和压力分别比2,4-二硝基甲苯的爆震速度和压力大21.7%和74.3%。使用核独立的化学位移分析来研究骨架的芳香性以及硝基-NNO--氧基和硝基基团对环芳香性的影响。静电势,键解离能,通过密度泛函理论估计了Mulliken电荷和Wiberg键序,以建立化合物的分子电子分布和稳定性。硝基-NNO-氮氧基比硝基具有更强的吸电子性能。
