In this review, the versatile and rich chemistry for the electrochemical reduction of substrates involving N−O bonds is surveyed. By the cathodic treatment of nitro, nitroso and other oxygenated organic nitrogen substrates, versatile and reactive intermediates are formed which can be subsequently converted to high value‐added products. In many examples, nitrogen heterocycles are selectively formed, but, also depending on the electrolytic conditions, free oximes, nitrones, amines and other entities can be obtained as well. The recent decades have witnessed two major advances – (i) going directly to more complex target molecules and (ii) conducting the electrolyses in much simpler set‐ups. Both improvements make the cathodic access of the target compounds much more practical and scalable.

涉及N-O键的底物电化学还原的最新进展

在这篇综述中，研究了用于电化学还原涉及N-O键的底物的通用且丰富的化学方法。通过对硝基，亚硝基和其他氧化有机氮底物进行阴极处理，可以形成通用的反应性中间体，然后可以将其转化为高附加值的产品。在许多实例中，选择性地形成氮杂环，但也取决于电解条件，也可以获得游离肟，硝酮，胺和其他实体。近几十年来，见证了两项重大进展-（i）直接用于更复杂的目标分子，以及（ii）以简单得多的设置进行电解。两项改进使目标化合物的阴极接触更加实用和可扩展。
