By reaction ofβ-diketones with zirconyl nitrate, zirconium bisacetylacetonate dinitrate and zirconium bisbenzoylacetonate were prepared.
By reaction ofβ-diketones with zirconyl nitrate in presence of sodium bicarbonate, zirconium trisacetylacetonate nitrate and zirconium trisbenzoylacetonate nitrate were prepared.
The reverse-disproportionation reaction is applicable to chelate zirconium compounds. Reaction of zirconium tetrakisacetylacetonate and of zirconium tetrakisbenzoylacetonate with the corresponding dinitrates gave the zirconium trisacylacetonate mononitrates.
The above-mentioned mono- and di-nitrates give double compounds with benzene and dioxane.
