R. China Received November 13, 2008; E-mail: guorong@ The Suzuki-Miyaura cross-coupling reaction of aryl halides with aryl boronic acids is one of the most powerful and convenient synthetic protocols for the generation of biaryl in organic chemistry. 铃木-宫浦反应中卤代芳烃和芳基硼酸交叉偶联生成联芳在有机化学中是最有权威性并且是最方便的合成方案的之一 In general, the catalysts of choice for Suzuki-Miyaurareaction is almost invariably palladium, although nickel and copper catalysts have been reported but with relatively low yields. 总体而言，铃木-宫浦反应中催化剂的选择几乎一成不变的都是钯，而根据报告镍和铜催化剂收益率相对而言低一些 In particular, gold complexes can also be used as efficient catalysts for such reactions. 详细来说，金的配合物在此类实验中一样可以作为有效的催化剂 Recently, the interest in palladium catalyst has shifted from palladium complexes to supported palladium nanoparticles, considering the simple separation and reusability of the catalyst. 最近，考虑到简单分离和催化剂的重复使用，钯催化剂逐渐由钯的复合物转变为纳米钯材料。
