| titleOfInvention | Process for the preparation of nickel (II) complexes containing a hetero-difunctional ligand and ethylene polymerization process with the complexes thus obtained |
| abstract | The invention relates to a process for preparing nickel (II) complexes containing heterodifunctional chelating ligands, comprising reacting a starting nickel (II) complex with either a compound of the formula (CF DRAWING IN BOPI) in in which Y is P, As or Sb, Z is O, S or Se and R1, R2, R3 and R4 are hydrogen atoms or hydrocarbon groups, optionally substituted, in the presence of a base, or with a corresponding compound to the formula (CF DRAWING IN BOPI) in which Y, Z, R1, R2, R3 and R4 have the meanings given above, and Q is a single charged cation. We thus obtain a nickel (II) complex containing a chelating anionic ligand [Y (R1) (R2) C (R3) = C (Z) R4] - linked to the nickel atom by the Y and Z atoms, which can be used for the polymerization of ethylene. |
