In chemistry, azoxy compounds are a group of organic compounds sharing a common functional group with the general structure R−N=N + (−O −)−R. [1] They are considered N-oxides of azo compounds. Azoxy compounds are 1,3-dipoles and cycloadd to double bonds. Most azoxy-containing compounds have aryl substituents.

氧化偶氮化合物 （英文：Azoxy）是 偶氮化合物 的 N-氧化物，通式写作RN=N + (-O −)R或R-N=N (→O)-R'。 相应的 官能团 称为 氧化偶氮基。 氧化偶氮基具有以下 共振式，因此它既是 1,2-偶极体，也是 1,3-偶极体： 它们可能具有 基因毒性。 亚硝基化合物 和 羟胺 衍生物失水 缩合 可以得到氧化偶氮化合物： 用 亚砷酸钠 或其他还原剂还原 硝基苯，会生成中间产物 苯胲 和 亚硝基苯。 它们相互作用，也会得到 氧化偶氮苯： [1] 以氧化偶氮苯为例，它还可通过 偶氮苯 的 三氧化铬 氧 …
