METHOD OF PRODUCING ENANTIOMERICALLY RICH 1-ETHYL-(3S)-CYCLOHEXYLALUMINACYCLOPENTANE Russian patent published in 2014 - IPC C07F5/06

Abstract RU 2536170 C2

FIELD: chemistry.

SUBSTANCE: invention relates to organometallic synthesis and specifically to a method of producing enantiomerically rich 1-ethyl-(3S)-cyclohexylaluminacyclopentane (1) . The method includes reacting an α-olefin with triethylaluminium (AlEt₃) in the presence of an enantiomerically pure catalyst of bis(1-neo-menthylene dienyl)zirconium dichloride ( $I n d_{2}^{*} Z r C l_{2}$ ). The α-olefin used is vinyl cyclohexane. The reaction is carried out in molar ratio vinyl cyclohexane:AlEt₃: $I n d_{2}^{*} Z r C l_{2}$ =25:(29-31):2 at 22°C for 24 hours in methylene chloride.

EFFECT: invention enables to obtain enantiomerically rich 1-ethyl-(3S)-cyclohexylaluminacyclopentane, which can be used in stereoregular polymerisation and oligomerisation of unsaturated compounds and as fine organic synthesis synthons.
