Dysprosium acetylacetonate is a chemical compound of dysprosium with formula Dy(C5H7O2)3(H2O)n.

Preparation and properties

Dysprosium acetylacetonate can be prepared by reacting dysprosium[1] or dysprosium hydride[2] with acetylacetone. Dy(acac)3·EtOH·0.5Hacac (where Hacac represents acetylacetone) can be obtained by electrolysis of dysprosium cathode in ethanol solution of acetylacetone, which can be heated to generate Dy(acac)3 through Dy(acac)3·EtOH.[3] It is a colorless solid. Its anhydrous form is stable in dry atmosphere and it forms a hydrate in humid air.[4] It can form Dy(acac)3·2CH3OH and Dy(acac)3·CH3OH·CH3CN in a methanol solution of acetonitrile.[5]

Applications

Dysprosium acetylacetonate can be used to catalyze the addition reaction of norbornene and carbon tetrachloride.[6] The dihydrate has been characterized by X-ray crystallography.[7]
