本文用β,β'-双环戊二烯基乙醚二钠与TiCl4, ZrCl4, (C5H5)TiCl3和FeCl2在四氢呋喃中反应合成了新型氧桥环戊二烯基钛、锆和铁衍生物。在企图合成硫桥环戊二烯基化合物时, 得到的却是四亚甲基桥联双环戊二烯基金属衍生物。(苯二亚甲基)双环戊二烯基二钠与FeCl2反应合成了对、间(苯二亚甲基)二茂铁。讨论了新化合物的X射线光电子能谱和Mossbauer谱。

Ring-oxadiethylene bridged bis(cyclopentadienyl) chlorides of titanium and zirconium I (M = Ti, Zr) were synthesized from the reaction of the disodium salt O(CH2CH2C5H4Na)2 with TiCl4 and ZrCl4, in THF. A similar reaction of the sulfur analog gave only the product of tetramethylene bridged bis(cyclopentadienyl)dititanium halides. Ring-phenylenedimethylene bridged ferrocene was synthesized from the disodium salt p-, m-C6H4(CH2C5H4Na)2 with FeCl2. The XPS and Moessbauer spectra of some compounds were discussed.
