摘要
硅基取代环戊二烯基二羰基铁负离子［η５－ＲＣ５Ｈ４Ｆｅ（ＣＯ）２］－＝（Ｒ＝ＳｉＭｅ３，Ｉ；Ｓｉ２Ｍｅ５，Ⅱ）与铁碘化合物（η－Ｃ５Ｈ５）Ｆｅ（ＣＯ）２Ｉ反应，除得到新的Ｆｅ－Ｆｅ化合物外，还分离到另两种母体Ｆｅ－Ｆｅ化合物；桥连化合物（η５，η５－Ｃ５Ｈ４ＳｉＭｅ２ＯＳｉＭｅ２Ｃ５Ｈ４）［Ｆｅ（ＣＯ）２Ｉ］２（６）与铁负离子［η５－Ｃ５Ｈ５Ｆｅ（ＣＯ）２］－（Ⅲ）的反应，仅分离到各自的母体Ｆｅ－Ｆｅ化合物，没有分离到预期的双ＦｅＦｅ化合物．结果表明上述反应并非单一的亲核反应过程，而存在着几种反应过程．
The reaction of silylcyclopentadienyl dicarbonyl iron anion[(η5-RC5H4 )Fe (CO)2]- (R=SiMe3, I; Si2Me5,Ⅱ)with η5-C5H5Fe (CO)2 I (4) gave expected new binuclear Fe-Fe complexes as well as the corresponding η5, η5-C5H.4SiMe2OSiMe2C5H4) [Fe (CO)2 I]2, (6) with the anion [η5-C5H4Fe(CO)2j(Ⅲ),only the parent Fe-Fe complexes were isolated. No new Fe-Fe species was obtained. The results reveals that the mechanism is not a simple nucleophilic process, but a more complex one.
