  Reactions of methyl- and ethylaluminium compounds with alkoxyalcohols. The influence of alkoxyalcohol substituents on the structure of the complexes formed

  摘要：

  Dimeric dimethylaluminium compounds {[Me2Al(mu-(OCH2CH2OPr)-Pr-n)](2) (1), [Me2Al(mu-OCH(CH3)(CH2OBu)-Bu-1)](2) (3), [Me2Al(mu-OCH2CH2CH2OEt)](2) (5), [Me2Al(mu-OCH2CH2CH(Me)OMe)](2) (7), [Me2Al(mu-OCH2CH2C(Me)(2)OMe)](2) (9)} and dichloroaluminium compounds {[Cl2Al(mu-(OCH2CH2OPr)-Pr-n)](2) (2), [Cl2Al(mu-OCH(CH3)(CH2OBu)-Bu-1)](2) (4), [Cl2Al(mu-OCH2CH2CH2OEt)](2) (6), [Cl2Al(mu-OCH2CH2CH(Me)OMe)](2) (8), [Cl2Al(mu-OCH2CH2C(Me)(2)OMe)](2) (10)} have been prepared. The molecular structures of compounds 2, 3, 6, 8, 9 and 10 have been determined by X-ray crystallography. All these compounds exist in the solid state as dimers with chelating ether-alkoxide ligands and five-coordinate aluminium atoms. Dichloroaluminium derivatives (compounds 2, 4, 6, 8 and 10) exist as five-coordinate isomers also in solution, while dimethylaluminium ones (compounds 1, 3, 5, 7 and 9) exist as an equilibrium mixture between four- and five-coordinate isomers. An increase of aluminium Lewis acidity in dichloroaluminium derivatives in comparison with dimethylaluminium ones results in substantial shortening of Al-O distances. The R2Al...O(ether)R' distance is mainly determined by the steric repulsion between the OR' group and the two alkyl substituents on aluminium. The influence of electronic properties of R' on Cl2Al...O(ether)R' interaction was illustrated for compound 2 in comparison with literature data for analogous complexes.
