  摘要：

  通过偶联α-烯烃，可以高产高选择性地制造线性1-丁烯二聚体和其他线性α-烯烃二聚体。偶联是通过将α-烯烃与铝基协同催化剂活化的铁基催化剂接触来完成的。催化剂的结构可防止形成多个二聚体产物，α-烯烃偶联的副产物几乎全部由甲基支链烯烃二聚体组成。这些二聚体在制药到塑料等领域具有潜在的多样化用途。线性1-丁烯二聚体可能特别有用于生产可塑剂醇，这些醇可以用于制造具有减少渗漏的高质量塑料。

  The synthesis of new iron(II) and vanadium(III) diiminepyridyl complexes is reported. The ligands were synthesized and characterized by GC/MS, 1H and 13C NMR spectroscopy. The corresponding complexes are characterized by mass spectrometry and in part by elemental analyses.

• Propylene bulk phase oligomerization with bisiminepyridine iron complexes in a calorimeter: mechanistic investigation of 1,2 versus 2,1 propylene insertion
  作者：Sebastian Thomas Babik、Gerhard Fink

  DOI：10.1016/s0022-328x(03)00670-3

  日期：2003.10

  Iron(II) complexes were synthesized with bisiminepyridine ligands of low steric demand. Activation with modified-methylaluminoxane (25 mol.% isobutyl groups) generated very active catalysts for propylene oligomerization. The oligomerizations were carried out in liquid propylene in a heat flow calorimeter. The oligomers were separated by preparative gas chromatography and the dimers and trimers analyzed using analytical gas chromatography, H-1-NMR- and C-13-NMR-spectroscopy. With knowledge of the dimer and trimer structure, we were able to establish a mechanistic pathway for propylene insertion and obtained knowledge about the iron alkyl species involved. Analysis of the various dimers formed allowed us to determine the percentage of 1,2 versus 2,1 propylene insertions. Considering the same iron alkyl species with ligands of different steric demand, a change in the probabilities for 1,2 versus 2,1 propylene insertions can be observed. With this knowledge, the catalyst behavior for ligands of varying steric demand can be predicted. (C) 2003 Elsevier B.V. All rights reserved.

  The synthesis of new iron(Pi) diiminopyridine complexes and their heterogenization to give highly active ethene polymerization catalysts is described. The ligands are characterized by (HNMR)-H-1, (CNMR)-C-13 spectroscopy and GC/MS. The complexes are paramagnetic and were characterized by elemental analyses and mass spectrometry. The complexes were activated and heterogenized with a cocatalyst consisting of partially hydrolyzed trimethylaluminum (PHT) on silica gel and were used for ethene polymerization.The polymerization results and the polymer properties are presented. The influence of the catalyst structure, hydrogen and 1-hexene on the polymerization behavior is discussed. (C) 2002 Elsevier Science B.V. All rights reserved.
