The present invention discloses a catalyst component based upon a Nib cluster made of two sheets each containing four nickel atoms and that is the reaction product of: a) a first component of the general formula (I) b) a second component based on complex, of the general formula (II) wherein in the first component, the benzene ring can be substituted in positions 3 and/or position and/or position 5 and/or position 6, wherein R and R′ are the same or different and can be selected from a phenyl, substituted or unsubstituted or a cycloalkyl or an alkyl having from 1 to 20 carbon atoms, wherein Q is a cation, and wherein, in the second component, R″ is selected from a halogen or an acetate and wherein the two arrows mean that there are two vacant sites. It also discloses a catalyst system and a process for the oligomerisation of olefins.
本发明揭示了一种基于Nib簇的催化剂组分,该簇由两个含有四个镍原子的片层构成,是以下反应的产物:a)通式(I)的第一组分;b)通式(II)的基于配合物的第二组分。其中,在第一组分中,苯环可以在3和/或4和/或5和/或6位置上被取代,其中R和R'相同或不同,可以选择为苯基,取代或未取代的环烷基或具有1至20个碳原子的烷基,其中Q是阳离子,在第二组分中,R"选择自卤素或醋酸根,并且两个箭头表示有两个空位。还揭示了一种催化剂系统和一种烯烃寡聚化的过程。
