乙酰丙酮鏑是一種配位化合物，化學式為Dy(C₅H₇O₂)₃，或簡寫為Dy(acac)₃。

製備及性質

乙酰丙酮鏑可由金屬鏑^[2]或三氫化鏑^[1]和乙酰丙酮反應製得。以鏑陰極在乙酰丙酮的乙醇溶液中電解，可以得到Dy(acac)₃·EtOH·0.5Hacac（其中Hacac表示乙酰丙酮），對其加熱，經Dy(acac)₃·EtOH生成Dy(acac)₃。^[3]其無水物在乾燥的氣氛中穩定，在潮濕空氣中形成水合物。^[4]它在乙腈的甲醇溶液中可以形成Dy(acac)₃·2CH₃OH和Dy(acac)₃·CH₃OH·CH₃CN。^[5]

用途

乙酰丙酮鏑可用於催化降冰片烯和四氯化碳的加成反應。^[6]
