A palladium‐catalyzed one‐step synthesis of (hetero)aryl alkyl sulfones from (hetero)arylboronic acids, potassium metabisulfite, and unactivated or activated alkylhalides is described. This transformation is of broad scope, occurs under mild conditions, and employs readily available reactants. A stoichiometric experiment has led to the isolation of a catalytically active dimeric palladium sulfinate
描述了由(杂)芳基硼酸,偏亚硫酸氢钾和未活化或活化的烷基卤化物以钯催化一步合成(杂)芳基烷基砜的方法。这种转化是广泛的,发生在温和的条件下,并使用容易获得的反应物。一个化学计量的实验导致了具有催化活性的二聚亚磺酸钯钯配合物的分离,该复合物通过X射线衍射分析进行了表征。
