CATALYST FOR SYNTHESIS OF 1-ETHYL-2,3-DIALKYL(PHENYL)ALUMINACYCLOPENT-2-ENES

摘要

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.;1 tbl, 1 ex
