A practical, efficient protocol was developed for the Suzuki reaction of aryl tosylates with arylboronic acids. The process was promoted by a nickel-based catalyst system consisting of the easily available Ni II -(σ-aryl) complex and the simple ligand PPh 3 in toluene in the presence of the base K 2 CO 3 . The convenient operation, high yield, generality, and low cost make this method viable for most
为芳基甲苯磺酸酯与芳基硼酸的 Suzuki 反应开发了一种实用、有效的方案。在碱K 2 CO 3 存在下,由易得的Ni II -(σ-芳基)配合物和甲苯中的简单配体PPh 3 组成的镍基催化剂体系促进了该过程。该方法操作方便、收率高、通用性强、成本低,适用于大多数普通实验室和大规模制备。
