A disila[2]ferrocenophane bearing a 9,9'-bi-9-9-silafluorene (9-silafluorene dimer) moiety as a bridging unit was synthesized and isolated as a stable crystalline compound. Disila[2]ferrocenophane newly obtained in this study, has been characterized by spectroscopic analyses, single crystal X-ray diffraction (SC-XRD) analysis, and electrochemical measurements. It was found that the obtained disila[2]ferrocenophane was reduced by a reducing agent to generate the corresponding 1,1'-ferrocenediyl-bis(silylanion) via the reductive Si-Si σ-bond cleavage. The trapping reactions of the 1,1'-ferrocenediyl-bis(silylanion) thus generated with electrophiles have also been attempted.
合成并分离出了一种以9,9'-联-9-9-硅芴(9-硅芴二聚体)部分作为桥连单元的二硅[2]二茂铁并环戊二烯,它是一种稳定的结晶化合物。本研究新得到的二硅[2]二茂铁并环戊二烯已通过光谱分析、单晶X射线衍射(SC-XRD)分析和电化学测量进行了表征。结果发现,所得到的二硅[2]二茂铁并环戊二烯可被还原剂还原,通过Si-Si σ键的还原裂解生成相应的1,1'-二茂铁二基双(硅阴离子)。还尝试了用亲电试剂对由此生成的1,1'-二茂铁二基双(硅阴离子)进行捕获反应。
