Description
By reaction of 3-acetyl-r-hydroxy-6-methyl-2H-pyran-2-one (HDh, dehydroacetic acid) with H2NR (R = Me, nPr or nBu) and HN(CH2CH2NH2)2 the related Schiff bases HDHR and H2Dh2T were obtained. All ligands react with uranyl nitrate yielding 1:2 adducts. In the uranyl acetate-HDhR systems adduct formation and ligand deprotonation should occur, depending on solvent, reaction time and hydration, whereas H2Dh2T undergoes total deprotonation in the presence of uranyl acetate to give [UO2(Dh2T)]. Ligands and complexes have been characterized by ir and nmr (1H and 13C) spectroscopy and, in some cases, by thermogravimetric measurements. The action of the amines on the preformed [UO2(Dh)2] complex is discussed
