METHOD OF PRODUCING 9-ETHYL-11-ALKYL-9-ALUMINABICYCLO[6,3,0]UNDEC-1(8)-ENES Russian patent published in 2009 - IPC C07F5/06

Abstract RU 2373214 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing 9-ethyl-11-alkyl-9-aluminabicyclo[6.3.0^1,8]undec-1(8)-enes of general formula (1): , R = C₄H₉, C₆H₁₃, C₈H₁₇, characterised by that, an equimolar mixture of cyclooctyne and α-olefin(hex-1-ene, oct-1-ene, dec-1-ene) is reacted with ethyl aluminium dichloride (EtAlCl₂) in the presence of magnesium (powder) and zirconocene dichloride catalyst (Cp2ZrCl₂) in molar ratio cyclooctyne : α-olefin : EtAlCl₂: Mg : Cp₂ZrCl₂ = 10 : 10 : (10-14): (10-14): (0.4-0.6) in an argon atmosphere at temperature 20°C and normal pressure in tetrahydrofuran for 8 to 12 hours. A new method is designed for producing 9-ethyl-11-alkyl-9-aluminabicyclo[6.3.0^1,8]udec-1(8)-enes with high regioselectivity, which can be used as components for catalyst systems in oligo- and polymerisation of olefin, diene and acetylene hydrocarbons, as well as in fine organic and organometallic synthesis.

EFFECT: improvement of method.
