The palladium–nickel binary nanocluster is reported as a new catalyst system for Suzuki–Miyaura cross-coupling of ortho-heterocycle-tethered stericallyhindered aryl bromides. The inferior results obtained with the reported Pd/Ni salts/complexes or individual Pd/Ni nanoparticles as catalyst reveal the cooperative catalytic effect of the Pd and Ni nanoparticles in the Pd–Ni nanocluster. The broad substrate
