摘　　要：由1,2,3-三硒[3]桥二茂铁(Ferrocenophane)经LiAlH_4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(C_5H_4Se)_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^(77)Se NMR谱及质谱分析。讨论了影响产率的因素和核磁共振图谱。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 NMR spectrum. A brief discussion on the relationship between the 1H and 77Se NMR spectra and the structure is given.
