  名称：

  The thermal metathesis reaction between SiSi and FeFe bonds of [Me2Si-η5-C5H3(SiMe2SiMe3)(CO)Fe(CO)2Fe(CO)-η5-C5H3(SiMe2SiMe3)SiMe2]. Regiospecific cleavage of the SiSi bond in the cyclic structure

  摘要：

  The reaction of ClMe2SiSiMe2Cl with LiC5H3SiMe2SiMe3 produces Me3SiSiMe2C5H3SiMe2SiMe2C5H3SiMe2SiMe3, which subsequently reacts with Fe(CO)(5) to give [Me2Si-eta(5)-C5H3(SiMe2SiMe3)(CO)Fe(CO)(2)Fe(CO)-eta(5)-C5H3(SiMe2SiMe3)SiMe2] (4) as a mixture of diastereomers. The rac and meso isomers of 4 (i.e. trans-4 and cis-4) may be separated completely by column chromatography and undergo the thermal metathesis reaction between their Si-Si and Fe-Fe bonds to give the rac and meso isomers of [Me2Si-eta(5)-C5H3(SiMe2SiMe3)Fe(CO)(2)SiMe2-eta(5)-C5H3(SiMe2SiMe3)Fe(CO)(2)] (5) (i.e. cis-5 and trans-5) in a stereospecific fashion. It is noteworthy that the metathesis reactions of trans-4 and cis-4 involve regiospecific cleavage of the Si-Si bond inside the cyclic structure with retention of those outside. Crystal and molecular structures of cis-4 and trans-5 have been determined by X-ray diffraction methods. (C) 2002 Elsevier Science B.V. All rights reserved.
