An efficient iodine/copper(II) oxide co‐promoted direct oxidative coupling of anilines and methyl aryl ketones has been developed for the synthesis of p‐amino‐substituted unsymmetrical benzils and their iodo‐substituted derivatives. The chemoselectivity of the reactions can be easily controlled by adjusting the amount of iodine. This method exhibits good functional group tolerance for various substituents
已开发出一种高效的碘/铜(II)共同促进苯胺和甲基芳基酮的直接氧化偶联反应,用于合成对氨基取代的不对称苯及其碘取代的衍生物。通过调节碘的量,可以容易地控制反应的化学选择性。该方法对甲基芳基酮的芳环上的各种取代基表现出良好的官能团耐受性。已经基于对照实验提出了该反应的可能机理。从苯甲醚产品中合成了几个代表性的喹喔啉,以证明该方法的实用性。
