制せい备[编辑]

1914年ねん，乙おつ酰丙酮钌通どおり过三さん氯化钌和わ乙おつ酰丙酮在ざい碳酸氢钾下した的てき反はん应首次じ合成ごうせい。^[3]从那时起，人にん们已经研究けんきゅう了りょう替がえ代だい合成ごうせい路ろ线，但ただし原始げんし的てき制せい备方法ほう仍然有用ゆうよう：^[4]

RuCl₃•3H₂O + MeCOCH₂COMe → Ru(acac)₃ + 3 HCl + 3 H₂O

结构和わ性せい质[编辑]

乙おつ酰丙酮钌有ゆう D₃ 对称性せい。六个氧原子以八面体构型围绕钌原子。乙おつ酰丙酮钌中ちゅう的てきRu-O 键长平均へいきん为 2.00 Å。^[1]由よし于 Ru(acac)₃ 是ぜ低てい自じ旋的，有ゆう一いち个d 电子，所以ゆえん是ぜ顺磁性せい的てき。Ru(acac)₃ 的てき磁化じか率りつ χかい_M为 3.032×10⁻⁶ cm³/mol，有效ゆうこう磁矩 μみゅー_eff为 1.66 μみゅー_B。^[5]在ざいDMF溶液ようえき中ちゅう，乙おつ酰丙酮钌的てき氧化电位为 0.593，还原电位-1.223 V（相あい对于二に茂しげる铁/二茂铁阳离子对）。^[6]

Ru(acac)₃在ざい烯烃存在そんざい下か还原会かい形成けいせい二に烯烃配合はいごう物ぶつ。通常つうじょう，此类反はん应是用よう锌在ざい乙おつ醇あつし（1,3-二に烯）^[7]中ちゅう或ある锌汞齐在ざい潮しお湿しめ的てき四よん氢呋喃中ちゅう进行的てき：^[8]

2 Ru(acac)₃ + 4 alkene + Zn → 2 Ru(acac)₂(alkene)₂ + Zn(acac)₂

产生的てき化合かごう物ぶつ是ぜ金属きんぞく烯烃配合はいごう物ぶつ的てき罕见例れい子こ，可か以可逆ぎゃく地ち维持氧化：

Ru(acac)₂(alkene)₂ ⇌ [Ru(acac)₂(alkene)₂]⁺ + e⁻

通つう过分离它和わ二苯甲酰基酒石酸的加合物，可か拆分为单独どく的てき对映异构体たい。^[9]
