TL;DR: In this article, the reaction activities for a series of benzylidenequinolin nickel complex systems were studied by density functional theory methods, and the energy gaps between Ni complex's lowest unoccupied molecular orbita (LUMO) and ethylene's highest occupied molecular orbital (HOMO) orbitals were calculated, regarding both pre-catalysts and active species.

TL;DR: A series of 2-(1-aryliminoethyl)-7-yrlimino-6,6-dimethylcyclopenta[b]pyridylchromium(III) chlorides was synthesized and characterized using FT-IR and elemental analysis, and the molecular structure of complex Cr1 was confirmed by using single-crystal X-ray diffraction to present a distorted octahedral geometry around the chromium center.

TL;DR: In this article, a template reaction of α,α′-dioxo-2,3:5,6-bis(hexamethylene)pyridine, iron(II) chloride tetrahydrate and corresponding aniline in acetic acid was used to synthesize polyethylene of high molecular weight.

TL;DR: In this article, the structure of tri(2-naphthyl)benzene has been confirmed by X-ray single crystal diffraction, and the tri-self-condensation of ketones was promoted by ti-tanium tetrachloride in toluene to afford corresponding benzene de- rivatives.

TL;DR: Upon activation with either methylaluminoxane (MAO) or ethylaluminum sesquichloride (EASC), all nickel complexes exhibited high activities towards ethylene polymerization, producing polyethylene with a relatively low degree of branching and narrow polydispersity.
