series of nickel(II) complexes have been synthesized and characterized. Molecular structure analysis exhibits that a square planar geometry around nickel is adopted. Upon activation with MAO, these nickel(II) complexes are efficient in catalyzing the ethylenedimerization, providing 1‐butene with an activity of up to 1.4×107 g/(mol·h·atm). The heteroatoms of the sidearm in the complexes were proved to
已经合成和表征了一系列镍(II)配合物。分子结构分析表明,采用了围绕镍的正方形平面几何形状。通过MAO活化后,这些镍(II)络合物可有效催化乙烯二聚,从而提供1-丁烯,其活性最高可达1.4×10 7 g /(mol·h·atm)。络合物中侧臂的杂原子被证明对1-丁烯的活性和选择性有很大的影响。
