Environmentally friendly oxidation of primary aliphatic amines to imines has been successfully achieved, under metal-free conditions, by the use of diverse electrogenerated o-azaquinone mediators. High catalytic performance, together with high chemoselectivity, were observed with electron-poor o-azaquinone catalysts generated from 2-aminoresorcinol derivatives. Similar to copper amine oxidase enzymes, these
通过使用多种电生成的邻氮杂醌介质,在无金属条件下已成功实现了伯脂肪族伯胺向亚胺的环保氧化。用由2-氨基间苯二酚衍生物生成的电子贫乏的邻氮杂醌催化剂观察到了高催化性能和高化学选择性。与铜胺氧化酶相似,这些介体对α-支链伯胺的反应性较低,而对仲胺的反应性较低。在缺少2-羟基的3,4-氨基苯酚衍生物的情况下,生成的邻氮杂醌类不能催化胺氧化成相应的亚胺。
