钯催化剂催化卤代芳烃和芳基硼酸生成碳-碳键的Suzuki偶联反应是合成联苯化合物的最重要的途径之一。相比于传统均相钯催化剂的利用率低,污染产品等缺点,磁性钯催化剂易回收,可重复利用,具有工业化应用前景,受到了广泛的关注。综述了近年来无配体磁性钯催化剂、无包裹磁性钯配体催化剂以及以碳、氧化硅、聚合物包裹的具有核壳结构的磁性钯配体催化剂的制备及其催化Szuki偶联反应的研究进展。
Palladium catalyst catalysing halogenated aromatics and aryl boronic acids to form carbon-carbon bonds Suzuki coupling reaction is one of the most important ways to synthesize biphenyl compounds. Compared with the disadvantages of low utilization rate of traditional homogeneous palladium catalysts and pollution products, magnetic palladium catalysts are easy to be recycled and can be reused, which has the prospect of industrial application and has drawn wide attention. In this paper, the preparation of magnetic palladium ligand catalyst with core-shell structure and its catalytic Szuki coupling reaction, which are ligand-free magnetic palladium catalyst, uncoated magnetic palladium ligand catalyst, and carbon, silica and polymer encapsulated in recent years are reviewed progress.
