摘要：
Treatment of AlMe3 with bidentate N, O-ligands, HOC(Me)(Ph)C6H4-NMe2-2 ((LH)-H-1) or HOC(CH2)(5)C6H4 -NMe2-2 ((LH)-H-2) in different molar ratios, four novel aluminum complexes [Me2AlOC(Me)(C6H5)C6H4-NMe2-2] (1), [Me2AlOC(CH2)C6H4-NMe2-2] (2), [Me2Al{OC(Me)(C6H5)C6H4-NMe2-2}(2)] (3) and [Me2Al{OC(CH2)(5)C6H4-NMe2-2}(2)] (4) were obtained in good yield. Complexes 1-4 were characterized by 1H and 13C NMR spectroscopy, elemental analyses and single crystal X-ray diffraction techniques. Each of the complexes 1, 2, 3 and 4 was tested for the capable of catalyzed Meerwein Ponndorf Verley (MPV) reduction of ketones or aldehydes with low catalyst loadings under mild conditions and showed good to excellent catalytic activities.
