Treatment of AlMe3 with bidentate N, O-ligands, HOC(Me)(Ph)C6H4-NMe2-2 (L1H) or HOC(CH2)5C6H4-NMe2-2 (L2H) in different molar ratios, four novel aluminum complexes [Me2AlOC(Me)(C6H5) C6H4-NMe2-2] (1), [Me2AlOC(Me)(CH2) C6H4-NMe2-2] (2), [Me2Al{OC(Me)(C6H5) C6H4-NMe2-2}2] (3) and[Me2Al{OC(Me)(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.
