摘要

硒促进的氧化使广泛的有价值的氧化官能团相互转换成为可能。苯胺在水中与过氧化氢在硒催化剂的存在下被氧化。硒催化剂决定了氧化产物的性质;硝基芳烃是用二苯二烯或苯二烯酸合成的，偶氮芳烃是用二氧化硒或硒酸钠合成的。反应机制依赖于Se(IV)活性氧化剂的反应活性，而Se(VI)物种已被证明不参与。

Synthesis of nitroarenes and azoxyarenes through the selenium-mediated on water oxidation of aryl amines

Selenium-promoted oxidations enable a broad range of valuable oxidative functional group interconversions. Anilines are oxidized with hydrogen peroxide in water in the presence of selenium catalysts. The selenium catalyst determines the nature of the oxidation product; whereas nitroarenes are obtained employing diphenyl diselenide or benzeneseleninic acid, azoxyarenes are formed using selenium dioxide or sodium seleninate. The reaction mechanism relies on the reactivity of Se(IV) active oxidants, while Se(VI) species have been demonstrated not to be involved in.
