| 摘 要： | 1,2-二(1-苯基环己基环戊二烯基)四甲基二硅烷与Fe(CO)5在二甲苯中加热回流生成二铁化合物(Me2SiSiMe2)(1-Ph-c-C6H10C5H3)Fe(CO)]2(μ-CO)2(2).通过柱层析分离到化合物2的顺反异构体2c和2t,并分别进行热重排反应,发现顺式底物2c重排生成反式重排产物Me2Si(c-C6H10PhC5H3)Fe(CO)2]2(3t),而反式底物2t重排则生成顺式重排产物3c.这表明重排反应是立体专一性的.通过X射线衍射分析测定了化合物2c和3t的晶体结构.

| Abstract: | The reaction of 1,2-bis(1-phenylcyclohexylcyclopentadineyl)tetramethyldisilane with Fe(CO)5in refluxing xylene afforded the diiron complex(Me2SiSiMe2)(1-Ph-c-C6H10C5H3)Fe·(CO)]2(μ-CO)2(2), existing as a mixture of cis and trans isomers(2c and 2t), which were separated by column chromatography.When the two isomers were heated in refluxing xylene, the cis substrate(2c) rearranged to the trans productMe2Si(1-Ph-c-C6H10C5H3)Fe(CO)2]2(3t), while the trans substrate(2t) yielded the cis product(3c), respectively.This indicates that the rearrangement reaction is stereospecific.The molecular structures of compound 3c and 4t were determined by X-ray diffraction analysis. |
