三氮烯(英語:Triazene),是一种不饱和无机化合物,化学式为N3H3。其结构中含有一个双键,是继二氮烯之后的第二种简单氮烯。

制备

[编辑]

三氮烯可以由受脉冲辐射分解得到[1]

用电子束激发固态NH3或者固态NH3-N2混合物使其升华,在升华气相产物中可以检测到三氮烯以及其同分异构体三亚胺(HNHNNH)的存在[2]

性质

[编辑]

三氮烯是一种不稳定的化合物,容易分解成氨和氮气。室温下在水中分解半衰期约在0.01s(酸性环境)至100s(弱碱环境)之间。三氮烯含有N=N双键,使得其存在顺反异构体。根据计算,三氮烯以反式三氮烯的形式存在,因为在热力学上,反式三氮烯的能量比顺式三氮烯低几kJ/mol,但反式三氮烯的分解涉及异构化变成顺式三氮烯中间体的过程[3]

衍生物

[编辑]

含有R1−N=N−NR2R3官能团结构的化合物被称为三氮烯类化合物[4],这类化合物在一些抗癌药物和染料有相关运用[5]
