  摘要：

  合成了几种带有8-苯胺-5,6,7-三氢喹啉配体的三价和五价钒配合物。这些钒络合物通过元素分析、FTIR 光谱和 NMR 进行了鉴定。进一步得到三价钒配合物V2、V3'、V4和五价钒配合物V5、V7的单晶，并通过X射线单晶衍射进行鉴定。此外，通过控制配体中取代基的电子和空间效应来调节这些催化剂的催化性能。在二乙基氯化铝存在下，配合物V5–V7显示出高活性（高达 82.8 × 10 6 g molV -1 h -1 )和对乙烯聚合良好的热稳定性。此外，对配合物V5-V7的共聚能力进行了评估，配合物V5-V7表现出高活性（高达105.6×10 6 g mol V -1 h -1）和对乙烯/降冰片烯共聚的高共聚能力。通过调整聚合条件，可以获得降冰片烯插入比例为8.1%~30.9%的共聚物。进一步研究了配合物V7的乙烯/1-己烯共聚作用，所得共聚物表现出适度的1-己烯插入率为1.2%。复合V7表现

  A new pair of plladium complexes (Pd4 and Pd5) ligated with constrained N-(5,6,7-trihydroquinolin-8-ylidene)arylamine ligands have been prepared and well characterized by 1H-, 13C-NMR and FTIR spectroscopies as well as elemental analysis. The molecular structure of Pd4 and Pd5 in solid state have also been determined by X-ray diffraction, showing slightly distorted square planar geometry around the palladium metal center. All complexes Pd1–Pd5 are revealed highly efficient catalyst in methyl acrylate (MA) polymerization as well as methyl acrylate/norbornene (MA/NB) copolymerization. In the case of MA polymerization, as high as 98.4% conversion with high molecular weight up to 6282 kg·mol−1 was achieved. Likewise, Pd3 complex has good capability to incorporate about 18% NB content into MA polymer chains. Furthermore, low catalyst loadings (0.002 mol %) of Pd4 or Pd5 are able to efficiently mediate the coupling of haloarenes with styrene affording up to 98% conversion.

  A series of N-(5,6,7-trihydroquinolin-8-ylidene)arylamine ligands was synthesized and fully characterized by NMR, IR spectroscopy and elemental analysis. Dimeric N-(5,6,7-trihydroquinolin-8-ylidene)arylaminonickel dichlorides were prepared and examined by IR spectroscopy and elemental analysis, and the molecular structures of the representative nickel complexes were determined by the single crystal X-ray diffraction. On treatment with various alkylaluminiums, all the title complexes exhibited highly active, single-site active behavior for ethylene polymerization producing polyethylene (PE) waxes. The catalytic systems using the co-catalysts diethylaluminium chloride (Et2AlCl) or methylaluminoxane (MAO) were investigated in detail, and the molecular weights and distributions of the PEs obtained were found to significantly rely on the nature of the different ligands present and reaction parameters such as the molar ratios of Al/Ni, reaction temperature and reaction time.

  合成了一系列 N-(5,6,7-三氢喹啉-8-亚基)芳胺配体，并通过核磁共振、红外光谱和元素分析对其进行了全面表征。制备了二聚 N-(5,6,7-三氢喹啉-8-亚基)芳基胺二氯化镍，并通过红外光谱和元素分析对其进行了检测，还通过单晶 X 射线衍射测定了代表性镍配合物的分子结构。用各种烷基铝处理后，所有标题配合物在乙烯聚合生成聚乙烯（PE）蜡的过程中都表现出高活性、单位活性行为。对使用二乙基氯化铝（Et2AlCl）或甲基铝氧烷（MAO）辅助催化剂的催化体系进行了详细研究，发现所获得的聚乙烯的分子量和分布在很大程度上取决于不同配体的性质以及反应参数，如铝/镍的摩尔比、反应温度和反应时间。

The solid state structures of representative complexes Pd3 and Pd4 were unambiguously confirmed by single crystal X-ray diffraction showing a slightly distorted square planar geometry around the palladium metal center. All these complexes have been found to be highly robust catalyst systems showing high catalytic activities toward the homopolymerization of methyl acrylate at elevated temperature
