differentiation of the two isomers of disubstituted tetrazoles are rarely studied, which is very important information for designing advanced materials based on tetrazoles. In this article, pairs of 2,5- and 1,5-disubstituted tetrazoles were carefully designed and prepared for study on their thermal decomposition behavior. Also, the substitution fashion of 2,5- and 1,5- and the substituents at C-5 position
诸如四唑之类的富氮化合物被广泛用作气体发生剂中的候选物。然而,很少研究双取代四唑的两种异构体的区别细节,这对于设计基于四唑的先进材料是非常重要的信息。在本文中,对2,5和1,5-二取代的四唑进行了精心设计和制备,以研究其热分解行为。同样,发现2,5-和1,5-的取代方式以及在C-5位置的取代基影响吸热或放热性质。据我们所知,这是第一次,不同四唑类化合物的热分解特性可以通过取代方式和取代基进行调节,它可以用作设计用于温度依赖型火箭的先进材料的有用平台。提出了aza-Claisen重排以了解吸热分解行为。
