Using a simple copper(I) catalyst has allowed a high yielding sulfonylative-Suzuki–Miyaura cross-coupling reaction to be developed. The process provides a single step route to diaryl sulfones from the direct combination of aryl boronic acids, sulfur dioxide and aryl iodides, and represents the first sulfonylative variant of a classic cross-coupling reaction. Sulfur dioxide is delivered from the surrogate
使用简单的铜(I)催化剂可以开发出高产率的磺酰化-Suzuki-Miyaura交叉偶联反应。该方法提供了从芳基硼酸,二氧化硫和芳基碘化物的直接组合制取二芳基砜的单步路线,并且代表了经典交叉偶联反应的第一个磺酰基化变体。二氧化硫由替代试剂DABSO输送。反应条件的变化允许磺酰化-Suzuki偶合的中断,从而导致推测的亚磺酸铜中间体的形成。这些亚磺酸盐可能会以其钠盐形式被捕集,并用亲电试剂进行处理,从而可以得到芳基烷基砜,β-羟基砜,磺酰胺和磺酰氟。
