Valuable aromatic nitrogen compounds can be synthesized by reduction of nitroarenes. Herein, we report electrochemical reduction of nitroarenes by a protocol that uses inert graphite felt as electrodes and ammonia as a reductant. Depending on the cell voltage and the solvent, the protocol can be used to obtain aromatic azoxy, azo, and hydrazo compounds, as well as aniline derivatives with high chemoselectivities
可以通过还原硝基芳烃来合成有价值的芳族氮化合物。在这里,我们报告了通过使用惰性石墨毡作为电极和氨作为还原剂的协议对硝基芳烃进行电化学还原。根据电池电压和溶剂的不同,该协议可用于获得芳族a氧基,偶氮和化合物以及具有高化学选择性的苯胺衍生物。该方案可以轻松放大至> 10 g,而产量不会降低,证明了其潜在的合成效用。提出了逐步的阴极还原途径以依次解释产物的世代。
