Synthesis, structure, and catalytic ethylene oligomerization of nickel(II) and cobalt(II) complexes with symmetrical and unsymmetrical 2,9-diaryl-1,10-phenanthroline ligands

10.1016/j.ica.2008.03.018

The research focuses on the synthesis, structural characterization, and catalytic ethylene oligomerization properties of nickel(II) and cobalt(II) complexes with symmetrical and unsymmetrical 2,9-diaryl-1,10-phenanthroline ligands. The study involves the preparation of ligands L1–L3 and subsequent formation of complexes 1–9 through reactions with nickel or cobalt dichloride or dibromide. The synthesized complexes were characterized using elemental analysis, UV–Vis, IR spectroscopy, and X-ray crystal structural studies. The catalytic activities of these complexes were evaluated in ethylene oligomerization reactions, utilizing methylaluminoxane (MAO) as a cocatalyst under varying conditions such as different Al/M molar ratios, temperatures, times, and ethylene pressures. The products were analyzed using gas chromatography (GC) and gas chromatography-mass spectrometry (GC–MS) to determine the distribution of oligomers and the yield of linear α-olefins. The experiments aimed to understand the influence of the ligand structure on the catalytic performance and to optimize the conditions for enhanced production of linear α-olefins, which are valuable industrial materials.
