Ni–Pd binary nanoclusters are reported for the activation of the C–O bond for Suzuki–Miyaura cross-coupling of bioactive heterocycle-tethered sterically hindered aryl carbonates with aryl boronic acids. The reaction does not take place in the presence of either the Pd or Ni salts/complexes or the individual Pd or Ni nanoparticles, indicating ensembling cooperativity between the Pd and Ni nanoparticles
据报道,Ni-Pd二元纳米团簇可激活Suzuki-Miyaura将具有生物活性的杂环束缚的空间受阻芳基碳酸酯与芳基硼酸的C-O键活化。该反应不会在Pd或Ni盐/络合物或单个Pd或Ni纳米粒子的存在下发生,这表明Pd和Ni纳米粒子在激活C-O键上具有协同作用。
