General Description

Trans-3-Methyl-2-pentene is a type of hydrocarbon that belongs to the class of organic compounds known as alkenes. These are unsaturated hydrocarbons with one or more carbon-carbon double bond. It is characterized by its five carbon atoms, with a double bond located between the second and third carbon atoms, and a methyl group attached to the third carbon atom. Due to its nature as an unsaturated hydrocarbon, it can participate in various reactions, including polymerization, oxidation, and other additive reactions. Trans-3-Methyl-2-pentene is less common in nature, but it's generally used in chemical industries for synthesis.

NNNO-Heteroscorpionate nickel (II) and cobalt (II) complexes for ethylene oligomerization: the unprecedented formation of odd carbon number olefins

The unprecedented observation of odd carbon number olefins is reported during nickel- catalyzed ethylene oligomerization. Two complexes based on Co (II) and Ni (II) with novel tetradentate heteroscorpionate ligand have been synthesized and fully characterized. These complexes showed the ability to oligomerize ethylene upon activation with various organoaluminum compounds (Et2AlCl, Et3Al2Cl3, EtAlCl2, MMAO). Ni (II) based catalytic systems were sufficiently more active (up to 1900 kg·mol (Ni)?1·h?1·atm?1) than Co (II) analogs and have been found to be strongly dependent on the activator composition. The use of PPh3 as an additive to catalytic systems resulted in the increase of activity up to 4,150 kg·mol (Ni)?1·h?1·atm?1 and in the alteration of selectivity. All Ni (II) based systems activated with EtAlCl2 produce up to 5 mol. percent of odd carbon number olefins; two probable mechanisms for their formation are suggested – metathesis and β-alkyl elimination.
