The combination of ArB(OH)2 transmetallation with cationic gold(I) [LAu]+ and electrochemical anodic oxidation (EAO) approach was successfully developed for the preparation of AuIII-Ar intermediate for the first time. This in-situ generated aryl gold intermediate gave rapid and controllable transmetallation with ArB(OH)2 or alkyne followed by reductive elimination to generate either di-aryl coupling or sp2-sp Sonogashira-type coupling products under mild conditions with no need of external oxidants, which significantly extended the versatility of electrochemical approach in promoting gold redox catalysis.

电化学金氧化还原催化选择性氧化芳构化

首次成功开发了将ArB（OH）2的金属转移与阳离子化的金（I）L +和电化学阳极氧化（EAO）的方法相结合的方法。这种原位生成的芳基金中间体可以在ArB（OH）2或炔烃的作用下快速且可控地进行金属转移，然后在温和条件下进行还原消除，从而生成二芳基偶联或sp2-sp Sonogashira型偶联产物，而无需使用外部氧化剂，这大大扩展了电化学方法在促进金氧化还原催化中的多功能性。
