  Stereospecific polymerization of 1,3-butadiene catalyzed by cobalt complexes bearing N-containing diphosphine PNP ligands

  摘要：

  A series of cobalt complexes bearing N-containing diphosphine PNP ligands has been synthesized and characterized. The nature of the ligand structure affects the binding of the ligand to the cobalt center and determines the coordination geometry of the cobalt complexes. All the complexes have been employed to catalyze the polymerization of 1,3-butadiene, in combination with methylaluminoxane (MAO) or ethylaluminum sesquichloride (EASC) as the cocatalyst. Both the nature of the ligand and the type of cocatalyst had a remarkable influence on the polymerization activity, microstructure and molecular weight of the resulting polymers. The [Co]/MAO catalytic systems resulted in relatively lower conversions of butadiene and cis-1,4 contents in the polymers than the corresponding [Co]/EASC catalytic systems. Upon activation with EASC, the polymerization behaviors of the catalytic systems were also affected by the reaction parameters. (C) 2012 Elsevier B.V. All rights reserved.

  A series of nickel(II) complexes ligated by the N-(1-(2-(diarylphosphino)phenyl)methylidene)quinolin-8-amines (P∧N∧N) and 2-(diphenylphosphino)-N-[2-(diarylphosphino)benzylidene]anilines (P∧N∧P) were synthesized and characterized by elemental analysis, spectroscopy, and X-ray crystallography. X-ray crystallographic analyses reveal complexes 16 and 20 as having a five-coordinated distorted trigonal-bipyramidal

  一系列镍（II）配合物通过连接Ñ - （1-（2-（二芳基膦）苯基）亚甲基）喹啉-8-胺（P ∧ Ñ ∧ N）和2-（二苯基膦基） - ñ - [2- （二芳基膦）亚苄基]苯胺（P ∧ ñ ∧ P）被合成和表征通过元素分析，光谱和X-射线晶体学。X射线晶体学分析表明，配合物16和20具有五坐标扭曲的三角-双锥体几何形状，而配合物12显示出扭曲的正方形-锥体几何形状，而配合物13则是扭曲的正方形平面。用MAO和AlEtCl 2激活后，这些配合物表现出相当高的乙烯低聚活性（高达1.34×10 6 g·mol - 1（Ni）·h - 1）。发现配体环境和反应条件显着影响催化剂的活性。另外，研究了具有扭曲的四面体配位几何形状的钴类似物，其显示出低的乙烯低聚活性。
