Herein, we have established a method for the construction of β-keto sulfones through aerobic oxy-sulfonylation of alkynes with sulfinates. The reaction performed employing air as the oxidant and oxygen source. Moreover, this protocol exhibits low consume of sulfinates, short reaction period, and minimal waste. Mechanism study and density functional theory (DFT) calculation showed that the solvent played
在此,我们建立了一种通过炔烃与亚磺酸盐的需氧氧磺酰化来构建 β-酮砜的方法。该反应使用空气作为氧化剂和氧源进行。此外,该协议表现出亚磺酸盐消耗低、反应周期短和浪费最少。机理研究和密度泛函理论(DFT)计算表明,溶剂在转化过程中起重要作用。
