METHOD OF PRODUCING ENANTIOMERICALLY RICH 1-ETHYL-(3R)-PHENYLALUMINACYCLOPENTANE

摘要

FIELD: chemistry.SUBSTANCE: invention relates to organometallic synthesis, specifically to a method of producing enantiomerically rich 1-ethyl-(3R)-phenylaluminacyclopentane (1). The method includes reacting a styrene with triethylaluminium (AlEt) in the presence of an enantiomerically pure catalyst of bis(1-neo-menthylene dienyl)zirconium dichloride (). The reaction is carried out in molar ratio styrene:AlEt:= 25:(29-31):2 at room temperature (22°C) for 24 hours without a solvent.EFFECT: invention enables to obtain enantiomerically rich 1-ethyl-(3R)-phenylaluminacyclopentane, which can be used in stereoregular polymerisation and oligomerisation of unsaturated compounds and as fine organic and organometallic synthesis synthons.1 tbl, 1 ex
