FIELD: chemistry.SUBSTANCE: invention relates to organometallic synthesis and specifically to a method of producing racemic 1-ethyl-3,4-bis[(oxyphenyl)methyl]aluminacyclopentanes of general formula (1a-d): a) R= R= H, R= OMe; b) R= H, R= R= OMe; c) R= R= R= OMe; d) R= H, R,R= OCHO. The method includes reacting unsaturated compounds with ethyl aluminium dichloride EtAlCland magnesium metal in the presence of a CpZrClcatalyst. The unsaturated compounds used are substituted allyl benzenes (allyl anisole, 4-allyl-1,2-dimethoxybenzene, 5-allyl-1,2,3-trimethoxybenzene, 5-allyl-1,3-benzodioxole). The reaction is carried out in molar ratio CpZrCl:Mg:EtAlCl:allyl benzene = (0.8-1.2):20:(25-50):20 at 20-30°C for 72 hours in tetrahydrofuran.EFFECT: compounds can be used as synthons for fine organic and organometallic synthesis.1 tbl, 2 ex |
