Preparation
Dysprosium acetate can be obtained by treating dysprosium oxide with acetic acid:[1]
- Dy2O3 + 6 CH3COOH → 2 Dy(CH3COO)3 + 3 H2O
Its hydrate, when heated to 150 °C in vacuum, yields the anhydrous triacetate.[5]
Reactions
Dysprosium(III) acetate tetrahydrate catalyzes the cyclization of 2-{[2-(phenylsulfonyl)hydrazinylidene]methyl}benzoic acid (BSHOPA) to form 2-(phenylsulfonyl)phthalazin-1(2H)-one (PSP).[6]
Dysprosium(III) acetate forms a variety of coordination polymers, e.g. with cymantrenecarboxylic acid.[7]
