CATALYST FOR SYNTHESIS OF 1-ETHYL-2,3-DIALKYL(PHENYL)ALUMINACYCLOPENT-2-ENES Russian patent published in 2011 - IPC B01J27/135 C07F5/06 C07F17/00

Abstract RU 2423178 C2

FIELD: chemistry.

SUBSTANCE: present invention relates to organoaluminium synthesis catalysts, specifically to a catalyst for synthesis of 1-ethyl-2,3-dialkyl(phenyl)aluminacyclopent-2-enes, which can be used as components of catalyst systems in oligo- and polymerisation of olefin, diene and acetylene hydrocarbons, as well as in fine organic and organometallic syntheses. The disclosed catalyst contains a Cp₂HfCl₂ complex.

EFFECT: Cp₂HfCl₂ catalyst enables to obtain desired products - 1-ethyl-2,3-dialkyl(phenyl)aluminacyclopent-2-enes without using pyrophoric initial "AOC" with high selectivity.
