Herein, a mild and operationally simple method for the Suzuki−Miyaura cross-coupling of boronic esters is described. Central to this advance is the use of the organic-soluble base, potassium trimethylsilanolate, which allows for a homogeneous, anhydrous cross-coupling. The coupling proceeds at a rapid rate, often furnishing products in quantitative yield in less than 5 min. By applying this method
在此,描述了一种温和且操作简单的硼酸酯的Suzuki-Miyaura交叉偶联方法。这一进步的中心是有机可溶性碱三甲基硅烷醇钾的使用,它可以实现均匀,无水的交叉偶联。偶联以快速的速度进行,通常在不到5分钟的时间内提供定量产量的产品。通过应用该方法,对于三个发表的反应,观察到反应时间减少了> 10倍,这需要> 48小时才能达到令人满意的转化率。
