chromatography. When the two isomers were heated in xylene, respectively, the cis substrate 3c rearranged to the trans product [Me2Si(η5-IndH4)Fe(CO)2]2 (4t), while the trans substrate 3t yielded the cis product [Me2Si(η5-IndH4)Fe(CO)2]2 (4c). This indicates that the rearrangement reaction is stereospecific, which is consistent with the result observed in the rearrangement of complex (Me2SiSiMe2)[(η5-t-BuC5H3)Fe(CO)]2(μ-CO)2
茚基配合物的催化氢化(ME 2 SiSiMe 2)[(η 5 -Ind)的Fe(CO)] 2(μ-CO)2(2)在CH 2
氯2得到的四氢络合物(ME 2 SiSiMe 2) [(η 5 -IndH 4)的Fe(CO)] 2(μ-CO)2(3),如现有的顺式和反式异构体的混合物(图3c和3吨),将其通过柱色谱法分离。当两种异构体分别在二
甲苯中加热时,顺式底物3c重新排列为反式产物[我2的Si(η 5 -IndH 4)的Fe(CO)2 ] 2(4吨),而反式基板3吨,得到顺式产物[我2的Si(η 5 -IndH 4)的Fe(CO )2 ] 2(4c)。这表明,重排反应是立体有择的,这与在重排中观察到的结果是一致的复杂(ME 2 SiSiMe 2)[(η 5 -叔- BUC 5 ħ 3)的Fe(CO)] 2(μ-CO)2个(5)。通过类似于基于5的详细研究提出的机制,描述了4的形成途径。通过X射
