METHOD OF PRODUCING 2-ALKYL-1,4-BIS(DIETHYLALUMINIO)BUTANES Russian patent published in 2012 - IPC C07F5/06

Abstract RU 2459828 C2

FIELD: chemistry.

SUBSTANCE: invention relates to organoaluminium synthesis and specifically a method of producing 2-alkyl-1,4-bis(diethylaluminio)butanes of general formula (1): (1), R=n-C₄H₉, n-C₆H₁₃, n-C₈H₁₇. The method involves reaction of α-olefins of general formula R-CH=CH₂, where R is as described above, with a second reactant in the presence of magnesium (Mg, powder) and a Cp₂ZrCl₂ catalyst in tetrahydrofuran at room temperature. The second reactant used is ethylene.

EFFECT: invention enables to obtain compounds which can be used as components of catalytic systems in oligomerisation and polymerisation of olefin, diene and acetylene hydrocarbons, as well as in fine organic and organometallic syntheses.
