Mg for B: An atom‐economical one‐pot synthesis by direct magnesium insertion in the presence of B(OBu)3 and LiCl allows a broad range of functionalized (hetero)aryl and alkenyl bromides to be converted into magnesium diorganoboronates 2, which undergo Suzuki–Miyaura cross‐coupling reactions with various aryl (pseudo)halides (see scheme). Both aryl groups of 2 are transferred and furnish the products
毫克乙:一个原子经济一锅合成通过在B存在(OBU)直接镁插入3和LiCl允许宽范围的官能化的(杂)芳基和链烯基溴化物以转换成镁diorganoboronates 2,其经历Suzuki-Miyaura与各种芳基(假)卤化物的交叉偶联反应(参见方案)。的两个芳基2被转印并在良好的产品提供优异的产率。
