Recent progress on nickel-based systems for ethylene oligo-/polymerization catalysis

• Full review on recent achievements of nickel complex pre-catalysts for ethylene oligo-/polymerization.
• Active species protected by steric influences of ligands present.
• Finely tuned ligands affecting the catalytic activities of the nickel complexes.
• Comparison between bi-dentate and tri-dentate ligands.
• Multi-nitrogen and heteroatom ligands.

Recent progress on nickel-based complex pre-catalysts is reviewed herein. The ethylene oligo-/polymerization behaviour is discussed in terms of the variation of the complex models bearing different kinds of ligand sets. These discussions focus mainly on the influence that the different substituents present have on the observed catalytic activity, the results of which can guide the design of new target structures possessing high ethylene activity.

Recent progress on nickel-based complex pre-catalysts for ethylene oligo-/polymerization is reviewed, indicating the influence of the different substituents present on the observed catalytic activity and providing guidelines for designing new highly active nickel species for ethylene activity.Figure optionsDownload as PowerPoint slide
