摘要: 由1,2,3-三硒[3]桥二茂铁(Ferrocenophane)经LiAlH4还原生成二硒酚,不经分离直接与一亲电试剂在三乙胺存在下反应,得到7种1,1′-二硒醚二茂铁,4种1,n-二硒[n]桥二茂铁(n=3~5)和1种螺形化合物[Fe(C5H4Se)2]2Sn。这12种化合物中有7种尚未见文献报道,对其中几种产物进行了77SeNMR 谱及质谱分析。讨论了影响产率的因素和核磁共振图谱。

Abstract: In this paper, an improved method for the synthesis of 1,1'-diselena substituted ferrocene derivatives is given.It involves the reduction of 1, 2, 3-triselena[3]ferrocenophane by LiAlH4 to form ferrocene 1,1'-diselenol, followed by the addition of an electrophile and triethy-lamine to the above reaction mixture to produce the title compounds in situ.Twelve such compounds were obtained, among which seven are new selenium-containing ferrocene derivatives.The structure of the products was identified by elemental analysis and 1H NMRspectrum.Abrief discussion on the relationship between the 1H and 77Se NMR spectra and the structure is given.

Key words: Ferrocene derivative, Organoselenium compound, Organic synthesis
