基于一种新的含恶二唑的三脚架结构，构建了一种自组装纳米Pd 6L 8（L = 1，3，5-tris（4′-pyridyoxadiazole）-2，4，6-trifluoride）球.在H_2 O-EtOH混合溶剂体系中，Pd（II）球在常温、低催化剂负载量、均相条件下对Suzuki-Miyaura偶联反应具有良好的催化性能。此外，它在邻二甲苯中显示出非均相催化剂性质，并且可以重复使用而不损失催化活性。
A self-assembled nano-sized Pd6L8 (L = 1,3,5-tris(4′-pyridyloxadiazole)-2,4,6-triethylbenzene) ball was constructed based on a new oxadiazole-containing tripod. In H2O–EtOH mixed-solvent system, Pd(II)-ball displays excellent performance in Suzuki–Miyaura cross-coupling reactions at low catalyst loading under ambient conditions in a homogeneous fashion. Furthermore, it shows heterogeneous catalyst nature in o-xylene and can be reused without loss of catalytic activity.
