FIELD: chemistry. ^ SUBSTANCE: invention relates to a method of producing 9-ethyl-11-alkyl-9-aluminabicyclo[6.3.01,8]undec-1(8)-enes of general formula (1): , R = C4H9, C6H13, C8H17, characterised by that, an equimolar mixture of cyclooctyne and -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 : -olefin : EtAlCl2: Mg : Cp2ZrCl2 = 10 : 10 : (10-14): (10-14): (0.4-0.6) in an argon atmosphere at temperature 20C and normal pressure in tetrahydrofuran for 8 to 12 hours. A new method is designed for producing 9-ethyl-11-alkyl-9-aluminabicyclo[6.3.01,8]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. ^ 1 cl, 1 tbl, 11 ex |
