structures of pentamethylcyclopentadienyl (Cp∗) rhodium(III) and rhodium(I) complexes. Dicationic rhodium(III) complexes, [Cp∗Rh(bpy)(MeCN)](PF6)2 and [Cp∗Rh(vbpy)(MeCN)](PF6)2 (bpy = 2,2′-bipyridyl and vbpy = 4-vinyl-2,2′-bipyridyl), were prepared by treatment of [Cp∗Rh(MeCN)3](PF6)2 with bpy and vbpy, respectively. The monocationic rhodium(III) complex, [Cp∗Rh(Me4phen)Cl]Cl (Me4phen = 3,4,7,8-tetramethyl-1
我们报告了五甲基环戊二烯基(Cp ∗)铑(III)和铑(I)配合物的合成和结构。阳离子铑(III)络合物[Cp ∗ Rh(bpy)(MeCN)](PF 6)2和[Cp ∗ Rh(vbpy)(MeCN)](PF 6)2(bpy = 2,2'-联吡啶和通过分别用bpy和vbpy处理[Cp ∗ Rh(MeCN)3 ](PF 6)2来制备vbpy = 4-乙烯基-2,2'-联吡啶基)。单阳离子铑(III)络合物[Cp ∗ Rh(Me 4 phen)Cl] Cl(Me 4phen = 3,4,7,8-四甲基-1,10-菲咯啉)是通过用Me 4 phen处理氯化物桥连的铑二聚体[Cp * RhCl 2 ] 2制备的。通过使用两种不同的方法还原相应的铑(III),可以合成两种铑(I)配合物:通过一种新方法生产Cp ∗ Rh(bpy),该方法涉及用甲酸al处理[Cp ∗ Rh(bpy)Cl] Cl在干燥乙腈中,用Na(Hg)还原[Cp
