Suzuki-Miyaura 反应，包含碳卤素的激活结合，特别 C-Cl 契约，因为他们的巨大的工业潜力，引起了普遍注意。然而，这些反应依赖于高度活跃、稳定的催化剂的发展。此处，我们开发了一个方便一个壶综合的湿线路 Pd _x Cu _y 为 Suzuki-Miyaura 反应的二金属的 nanocrystals。由介绍 Cu，一个地球丰富的元素，当要求的 Pd 的数量被减少时，催化活动极大地被提高。Pd _x 不同作文的 Cu _y nanocrystals，包括 Pd ₃ Cu， Pd ₂ Cu， PdCu， PdCu ₂, 和 PdCu ₃, 被调节 Pd 成功地综合: Cu 比率。他们在在 phenylboronic 酸和 halobenzenes (iodo- ， bromo- ，或 chlorobenzene ) 之间的 Suzuki-Miyaura 反应的催化表演证明 PdCu ₃ nanocatalyst 表明了最好的功效。

英文摘要：

Suzuki-Miyaura reactions, involving the activation of carbon-halogen bonds, especially C-C1 bonds, have drawn widespread attention because of their huge industrial potential. However, these reactions are dependent on the development of highly active and stable catalysts. Herein, we developed a convenient one-pot wet route to synthesize PdxCuy bimetallic nanocrystals for the Suzuki-Miyaura reaction. By introducing Cu, an earth-abundant element, the catalytic activity was greatly enhanced while the amount of Pd required was reduced. PdxCuy nanocrystals of different compositions, including PdBCu, Pd2Cu, PdCu, PdCu2, and PdCu3, were successfully synthesized by tuning the Pd：Cu ratio. Their catalytic performance in Suzuki-Miyaura reactions between phenylboronic acid and halobenzenes （iodo-, bromo-, or chlorobenzene） showed that PdCua nanocatalyst demonstrated the best efficacy.
