摘　　要：通过静电吸引策略将具有高度分散性的原子精确纳米团簇[Pd3Cl(PPh2)2(PPh3)3]+(Pd3Cl)负载在介孔SBA-15棒上。结构明确的Pd3Cl/SBA-15催化剂在以水作为溶剂以及温和的反应条件下对催化Sonogashira碳-碳偶联反应展现了较好的催化性能以及循环性。在此基础上,我们研究了Pd3Cl团簇结构与性能之间的关系,并证实内核的Pdδ+(0<δ<2)与配体之间的协同效应是催化反应的关键。In this work,atomically precise[Pd3Cl(PPh2)2(PPh3)3]+(denoted as Pd3Cl)nanoclusters with high monodispersity were supported on the rod-like mesoporous SBA-15 by electrostatic attraction strategy.The well-defined Pd3Cl/SBA-15 catalysts exhibited good catalytic performance and recyclability for Sonogashira C-C coupling reaction under mild condition with environment-friendly water as solvent.Importantly,we investigated the relationship between structures and properties of Pd3Cl,which demonstrated that the synergistic effect between Pdδ+(0<δ<2)and the ligand was the key to the catalytic reaction.
