2-(5-Phenylpyrazol-3-yl)-8-arylimino-5,6,7-trihydroquinolyliron Chlorides as Precatalysts for Ethylene Oligomerization

Year: 2025

Type: article

Abstract: A series of 2-(5-phenylpyrazol-3-yl)-8-arylimino-5,6,7-trihydroquinolyliron chlorides (Fe1–Fe6) have been prepared and characterized by FT-IR spectra and elemental analysis. In single-crystal X-ray crystallography, Fe4 shows a distorted trigonal–bipyramidal geometry along with a self-assembling network through intermolecular NH···HO and OH···Cl hydrogen bonding. In the presence of MAO, all iron complexes perform with good activity and high selectivity for 1-butene. In addition, mixed solvents with different ratios of methylcyclohexane and toluene have been explored with a view to optimizing the catalytic performance.
