The mono(acetylacetonato) complexes [MCl(O,O'-acac)(η6-arene)] (M = Ru, Os, arene = C6H6, 1,3,5-C6H3Me3, C6Me6; M = Os, arene = 1,2-C6H4Me2, 1,2,3-C6H3Me3), which are formed from [MCl2(η6-arene)]2 and thallium or sodium acetylacetonate, react with thallium acetylacetonate to give bis(acetylacetonato) complexes [M(O,O'-acac)(η1-acac)(η6-arene)]. The η1-acac ligand is bound through the gamma-carbon atom
单(乙酰丙酮)配合物 [MCl(O,O'-acac)(η6-arene)] (M = Ru, Os, arene = C6H6, 1,3,5-C6H3Me3, C6Me6; M = Os, arene = 1 ,2-C6H4Me2, 1,2,3-C6H3Me3) 由 [MCl2(η6-arene)]2 和铊或乙酰丙酮钠形成,与乙酰丙酮铊反应生成双(乙酰丙酮)络合物 [M(O,O) '-acac)(η1-acac)(η6-芳烃)]。对于 M = Ru、Os、芳烃 = C6H6,η1-acac 配体通过 γ-碳原子结合;M = Os, 芳烃 = 1,2-C6H4Me2, 1,2,3-C6H3Me3 并通过酮氧原子为 M = Ru, Os, 芳烃 = 1,3,5-C6H3Me3, C6Me6,差异归因于立体效应和电子效应的结合。阳离子钌 (II) 衍生物 [Ru(L)(O,O'-acac)(η6-芳烃]+
