METHOD OF PRODUCING 1-ETHYL-3-ALKYLALUMINIUM CYCLOPENTANES Russian patent published in 2011 - IPC C07F5/06

Abstract RU 2433132 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing 1-ethyl-3-alkylaluminium cyclopentanes of general formula (1): (1), where R=n-C₄H₉, n-C₆H₁₃, n-C₈H₁₇. The method involves reaction of α-olefins R-CH=CH₂ (where R= n-C₄H₉, n-C₆H₁₃, n-C₈H₁₇) with EtAlCl₂ in the presence of Mg and a Cp₂ZrCl₂ catalyst at room temperature in a tetrahydrofuran (THF) solvent for 6-8 hours. Ethylene is fed into the reaction mass at excess pressure of 0.2 atm. Molar ratio R-CH=CH₂:EtAlCl₂:Mg:Cp₂ZrCl₂ = 10:(10-18):(10-14):(0.3-0.7).

EFFECT: method increases output and cuts reaction time.
