  Highly active, cheap, and easy to synthesize catalytic systems, obtained in situ by the oxidative addition of salicylaldimine ligands to bis(1,5‐cyclooctadiene)nickel(0) and activated by methylaluminoxane (MAO), are now reported for the vinyl polymerization of norbornene. Their activity resulted mainly influenced by the nature of the substituents present both on the phenolate moiety and on the N‐aryl

  现在报道了乙烯基聚合反应中高活性，廉价且易于合成的催化体系，该催化体系是通过将水杨醛亚胺配体氧化加成到双（1,5-环辛二烯）镍（0）上并经甲基铝氧烷（MAO）活化而获得的。降冰片烯。它们的活性主要受酚盐部分和N-芳基环上存在的取代基的性质以及市售MAO中存在的游离三甲基铝（TMA）含量的影响。特别是当3,5-二硝基-N-（2,6-二异丙基苯基）水杨醛亚胺配体与Ni（cod）2结合使用时，可以确定最大活性，高达约78,000 kg聚降冰片烯/ mol Ni×h和TMA耗尽的MAO。据我们所知，采用这种更具可持续性的反应介质可以达到这种卓越的性能，这是从未报道过的在甲苯而不是氯代芳烃中达到的最高性能。还研究了反应时间，温度，单体/镍和铝/镍摩尔比等主要反应参数对催化剂性能和聚合物性能的影响。©2012 Wiley Periodicals，Inc.

• Structural characterization of nitro-substituted phenoxyiminato nickel complexes; inter-molecular π–π interactions in the solid states and effect of the electron drawing groups on catalytic activity

  Three phenoxyiminato nickel complexes [(L)Ni(PPh3)(Ph)] have been prepared by the introduction of the electron drawing nitro substitutes on ortho or para-position of phenoxy and characterized by X-ray crystallography. Experimental and theory calculation suggested that the ortho and para nitro groups may be equally responsible for the small net charge on the central metal atoms because the interplanar angles between o-nitro planes and aromatic rings (28.7-37.3 degrees) are much higher than those between p-nitro planes and aromatic rings (8.2-13.8 degrees). In the solid states of these nickel complexes there exist the short inter-molecular p-p stacking interactions with the distances of 3.5828 angstrom (ortho-nitro), 3.5844 angstrom (para-nitro), and 3.0929 angstrom (ortho- and para-nitro) between two neighboring nitro-phenyl moieties.
