| 摘要: 通过调变溶剂热的反应条件,我们合成了3种Ni(Ⅱ)基的配位聚合物(CPs)[Ni (CH3-BDC)(3-TBT)(H2O)2]·EtOH·2H2O (CP1)、[Ni3(CH3-BDC)3(3-TBT)2(H2O)5]·2DMF·2H2O (CP2)和[Ni3(CH3-BDC)3(3-TBT)2(H2O)6]·2DMF·4H2O (CP3),其中CH3-H2BDC=5-methyl isophthalic acid,3-TBT=2,4,6-tris (3-pyridyl)-1,3,5-benzene。X射线单晶衍射分析表明,3个CPs都是由相似的Ni2(CH3-BDC)2的双核单元构建的,并分别呈现出从零维(0D)、2D到3D结构的网络骨架。反应条件的微小调变,导致了不同结构的配位聚合物。同时,催化实验表明,3在无溶剂的温和反应条件下,CP3对苄醇及其衍生物与苯胺的氧化-偶联反应表现出极好的催化活性和循环稳定性。 | |

| Abstract: By tuning the solvothermal reaction conditions, we prepared three Ni(Ⅱ)-based coordination polymers (CPs), namely[Ni(CH3-BDC)(3-TBT)(H2O)2]·EtOH·2H2O (CP1),[Ni3(CH3-BDC)3(3-TBT)2(H2O)5]·2DMF·2H2O (CP2), and[Ni3(CH3-BDC)3(3-TBT)2(H2O)6]·2DMF·4H2O (CP3), where CH3-H2BDC=5-methyl isophthalic acid, 3-TBT=2,4,6-tris(3-pyridyl)-1,3,5-benzene. X-ray single crystal diffraction analyses reveal that three CPs are constructed from similar Ni2(CH3-BDC)2 binuclear units and exhibited different zero-dimensional (0D), 2D, and 3D networks, respectively. Meanwhile, the catalytic experiments show that CP3 exhibits the best catalytic activities and cycle stability for the oxidative coupling reaction of benzyl alcohol and its derivatives with aniline under solvent-free conditions.
