ClMe2SiSiMe2Cl顺序与茚基锂和环戊二烯基锂作用,生成(1-C9H7)Me2SiSiMe2C5H5.后者进一步与五羰基铁反应,得到硅硅桥联茚基环戊二烯基化合物[η5,η5-(1-C9H6)Me2SiSiMe2C5H4]Fe2(CO)4 (2).化合物2在加热条件下发生重排反应,给出硅硅键和铁铁键复分解产物([-)Me2Si(η5-1-C9H6)Fe(CO)2SiMe2(η5-C5H4)Fe(CO)2(]-) (3).利用X射线衍射法,测定了2和3的分子结构.

The reaction of ClMe2SiSiMe2Cl in turn with indenyllithium and cyclopentadienyllithium afforded (1-C9H7)Me2SiSiMe2C5H5. The latter reacted subsequently with Fe(CO)5 giving the Si—Si bond-bridged indenyl and cyclopentadienyl complex [η5,η5-(1-C9H6)Me2SiSiMe2C5H4]Fe2(CO)4 (2). Complex 2 underwent the rearrangement reaction under thermal conditions to give a product （-[Me2Si(η5-1-C9H6)Fe(CO)2SiMe2(η5-C5H4)Fe(CO)2(]-) (3) through metathesis of the Si—Si and Fe—Fe bonds. The molecular structures of 2 and 3 have been determined by X-ray diffraction methods.

Key words: rearrangement, Si—Si bond, Fe—Fe bond, crystal structure
