A copper-catalyzed cross-dehydrogenative coupling (CDC) reaction between aromatic aldehydes and DMSO was developed, which afforded β-keto sulfoxides in 73–92% yields. The reaction process involved base-promoted DMSO addition to aldehydes, and copper-catalyzed aerobic oxidation. Furthermore, the aromatic alcohols which could be oxidized to aldehydes are also suitable substrates for this catalytic system
开发了芳香醛和 DMSO 之间的铜催化交叉脱氢偶联 (CDC) 反应,以 73-92% 的产率提供β-酮亚砜。反应过程涉及碱促进的 DMSO 加成醛,以及铜催化的有氧氧化。此外,可被氧化成醛的芳香醇也是该催化体系的合适底物。
