METHOD FOR COMBINED PREPARING 1-ETHYL-2-ALKYL-3-[1'-ETHYLALUMACYCLOPENT-3'-YL)METHYL]-ALUMACYCLOPENT-2-ENES AND 1-ETHYL-2-[1'-ETHYLALUMACYCLOPENT-3'-YL)METHYL]-3-ALKYLALUMACYCLOPENT-2-ENES Russian patent published in 2004 - IPC

Abstract RU 2231528 C2

FIELD: chemistry of organometallic compounds, chemical technology.

SUBSTANCE: invention relates to a method for preparing new organic-organic compounds that can be used as a component of catalytic systems in processes of oligomerization and polymerization of olefinic and diene hydrocarbons and in the fine organic and organometallic syntheses. Invention describes a method for preparing 1'-ethyl-2-alkyl-3-[1-ethylalumacyclopent-3'-yl)methyl]-alumacyclopent-2-enes of the formula (1)

and 1-ethyl-2-[1'-ethylalumacyclopent-3'-yl)methyl]-3-alkylalumacyclopent-2-enes of the formula (2)

wherein R means n-C4H9, n-C5H11, n-C7H15 by interaction of 1-alkyl-2-allylacetylene of the general formula with triethylaluminum of the formula AlEt3 in the mole ratio R-≡-CH2CH=CH2 : EtAl3 = 10:(30-40) mole % in the presence of two-component catalyst zirconocene dichloride - diisobutylaluminum chloride of the formula (Cp2ZrCl2-Bui2

AlH) in the amount 8-12 mole % with respect to 1-alkyl-2-allylacetylene in argon atmosphere, at room temperature 21-22 C for 6-10 h. Invention provides preparing new cyclic dialuminum compounds.

EFFECT: improved preparing method.
