Abstract
Abstract Reactions of bis(β-diketonato)aluminium(III)-di-μ-isoproxo-di-isopropoxo aluminium(III), [(CH3COCHCOR)2Al(μ-OPri)2Al(OPri)2] with 8-hydroxyquinoline, C9H6NOH in 1 : 1 and 1 : 2 molar ratios, have resulted in the synthesis of [(CH3COCHCOR)2Al(μ-OPri)2Al(ONC9H6)(OPri)] and [(CH3COCHCOR)2Al(μ-OPri)2Al(ONC9H6)2], respectively. These are soluble in a variety of organic solvents (e.g. benzene, chloroform and dimethylsulfoxide), except [(CH3COCHCOCH3)2Al(μ-OPri)2Al(ONC9H6)2] and [(CH3COCHCOOC2H5)2Al(μ-OPri)2Al(ONC9H6)2], which are insoluble in benzene but soluble in chloroform and dimethylsulfoxide. These derivatives show dinuclear behaviour in chloroform. Plausible structures have been proposed on the basis of elemental analyses, molecular weight measurements, IR and NMR (1H, 13C and 27Al) spectral studies. 27Al NMR spectra show the presence of six and four/five coordinated aluminium sites.
