摘要
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。
The Suzuki cross-coupling reactions catalyzed by palladium catalysts to form the carbon-carbon bonds between aryl halides and aryl boronic acids is one of the most important way of synthesizing biphenyl compound. Compared with the traditional homogeneous catalysts whose disadvantages are low catalyst recycling rate and polluting products, magnetic palladium-based catalysts are easy separable and recycled, which is suitable for industrial application and attracts much greater attention. This paper introduces some latest development process in the preparation of no-ligand magnetic palladium catalysts, palladium-based catalysts supported on no-coated magnetic particles and shell-core structure palladium-based catalysts support on magnetic particles coated by the materials, such as carbons, silica, polymers and their application in Suzuki reactions.
