An effective synthetic approach for various 1,2,2-triarylethanones from triaryl substituted alkenes has been developed via an electrochemical Wacker-type oxygenation with O2 as the sole oxygen source. It presents the first instance of the Wacker-type oxidation expanding its substrate scope to trisubstituted alkenes. The approach is transition-metal-free, compatible with various functional groups, and
通过以 O 2作为唯一氧源的电化学瓦克型氧化,开发了一种从三芳基取代的烯烃中有效合成各种 1,2,2-三芳基乙酮的方法。它提出了瓦克型氧化将其底物范围扩展到三取代烯烃的第一个实例。该方法不含过渡金属,与各种官能团相容,并且可以在温和的条件下进行,从而获得令人满意的产率。机械实验表明 C O 键的形成是通过阳离子碳物质和超氧自由基之间的反应发生的,其中涉及富电子取代基的 1,2-位移。
