acryloyloxylation of ketones with α,β-unsaturated carboxylic acids was developed through using copper (I) as the catalyst. The most concise approach to form α-acryloyloxyketones through direct oxidative coupling at α-C(sp3)-H of ketones. This method had a high productivity for the products and a wide range of application for both ketones and unsaturated carboxylic acids. A copper (I) catalyzed reaction mechanism
通过使用铜 (I) 作为催化剂开发了酮与 α,β-不饱和羧酸的有效 α-CH 丙烯酰氧基化。通过在酮的 α-C(sp3)-H 处直接氧化偶联形成 α-丙烯酰氧基酮的最简洁方法。该方法对产品的生产率高,对酮类和不饱和羧酸均有广泛的应用。通过对照实验提出了铜(I)催化的反应机理。
