摘要:
                                Reactions of bis(beta-diketonato)aluminium(Ill)-di-mu-isopro-poxo-di-isopropoxoaluminium(III), [(CH3COCHCOR)(2)Al-(mu-OPr-i)(2)Al(OPr-i)(2)] with 2-pyridylmethanol, (C5H4N-2CH(2)OH) in 1:1 and 1:2 molar ratios in refluxing anhydrous benzene resulted in the synthesis of [(CH3COCHCOR)(2)Al(mu-OPr-i)(2)Al(OCH2-2-C5H4N)(OPr-i)] [where R = CH3 (1), -OC2-H-5 (3), and -C6H5 (5)] and [(CH3COCHCOR)(2)Al(mu-OPr-i)(2)Al(OCH2-2-C5H4N)(2)] [where R = CH3 (2), -OC2H5 (4), and -C6H5 (6)], respectively. All of these compounds are sharp melting solids and are soluble in a variety of organic solvents (e.g., benzene, chloroform and dimethyl sulfoxide) except [(CH3COCHCOOC2H5)(2)Al(mu-OPr-i)(2)AI(OCH2-2-C5H4N)(2)], which is insoluble in benzene but soluble in chloroform and dimethylsulfoxide. All of these derivatives show a dinuclear structure in benzene. All of the above derivatives have been characterized by elemental analyses, molecular weight determinations, IR and NMR (H-1, C-13 and Al-27) and FAB mass spectral studies.
