Dedicated to Prof. Helgard G. Raubenheimer on the occasion of his 65thbirthday

The imide derivatives Li4Ti4O2(NR)2(OiPr)12 (R = CH2C6H5, C6H11, C4H9) were obtained either by reaction of the amine adduct Ti2(OiPr)8(H2NR)2 with lithium di- iso-propylamide or butyllithium, or when the primary amine was first reacted with the base and then with Ti(OiPr)4. T he structures of the imide derivatives are the same as that of Li4Ti4O4(OiPr)12 (= Li4Ti4(µ2-O)2(µ5-O)2(µ2-OiPr)4(µ3- OiPr)4(OiPr)4) with the twoµ2-oxo groups replaced by two µ2-NR groups.

Key words:Titanium Alkoxide Derivatives, Lithium Alkoxide Derivatives, Imide Ligands
