Suzuki–Miyaura reactions, involving the activation of carbon–halogen bonds, especially C–Cl 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 Pd_xCu_y 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. Pd_xCu_y nanocrystals of different compositions, including Pd₃Cu, 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 PdCu₃ nanocatalyst demonstrated the best efficacy.
