A simple bioinspired ortho-quinone catalyst for the aerobic oxidative dehydrogenation of amines to imines is reported. Without any metal cocatalysts, the identified optimal ortho-quinone catalyst enables the oxidations of α-branched primary amines and cyclic secondary amines. Mechanistic studies have disclosed the origins of different performances of ortho-quinone vs para-quinone in biomimetic amine oxidations.
报道了一种简单的仿生邻醌催化剂，用于胺的有氧氧化脱氢反应生成亚胺。在没有任何金属共催化剂的情况下，所鉴定的最佳邻醌催化剂能够实现α-支链伯胺和环状仲胺的氧化。机理研究揭示了邻醌与对醌在仿生胺氧化中表现不同的原因。
