oxidation of various hydroquinones was achieved by using copper nanoparticles entrapped in aluminum oxyhydroxide [Cu/AlO(OH)] at room temperature. Furthermore, 2,5-diamino-1,4-benzoquinones were synthesized directly from hydroquinone and amines by a one-pot procedure consisting of the copper-catalyzed aerobic oxidation of hydroquinones and the double addition of amines to the resulting quinones.
在室温下,通过使用羟基氧化铝[Cu / AlO(OH)]截留的铜纳米颗粒,可实现各种对苯二酚的好氧氧化。此外,通过一锅法直接由对苯二酚和胺合成2,5-二氨基-1,4-苯醌,该一锅法由铜催化的对苯二酚好氧氧化和向所得醌双加胺。
