桥环二茂钛、锆、铁金属衍生物的研究

Studies on Ring-Bridged Bis (cyclopentadienyl)metal (Ⅳ B) and Iron Derivatives

本文用β,β′-双环戊二烯基乙醚二钠与TiCl_4,ZrCl_4,(C_5H_5)TiCl_3和FeCl_2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FeCl_2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 and fluorides of titanium and zirconium were synthesized from the reaction of the disodium salt O(CH_2CH_2C_2H_4Na)_2 with TiGl_4, ZrCl_4, (C_5H_5)TiCI_3, and FeCl_2 in THF. A similar reaction of the sulfur analog gave only the product of tetramethylene bridged bis(cyclopentadienyl)dititanium halides. Ring-phenylene dimethylene bridged ferrocene was synthesized from the disodium salt p-, m-C_6H_4 (CH_2C_5H_4Na)_2 with FeCl_2. The XPS and Mssbauer spectra of some compounds were discussed.
