  Synthesis and characterization of a series of sila-bridged diiron complexes (E)[(η5-t-BuC5H3)Fe(CO)]2(μ-CO)2 (E=Me2Si, Me2SiSiMe2, Me2SiOSiMe2). The molecular structures of cis- and trans-(Me2Si)[η5-t-BuC5H3)Fe(CO)]2(μ-CO)2

  摘要：

  Binuclear iron complexes (E)[(eta(5)-t-BuC5H3)Fe(CO)](2)(mu-CO)(2) [E = Me2Si (1), Me2SiOSiMe2(3)] were prepared by reaction of Fe(CO)(5) with the corresponding cyclopentadienyl ligands in boiling xylene. Like the analogue (Me2SiSiMe2)[(eta(5)-t-BuC5H3)Fe(CO)](2)(mu-CO)(2) (2) reported previously, they are also found to exist as a mixture of cis and trans isomers that have been separated by preparative TLC. To examine the effect of larger substituents on the formation of isomers, the analogue (Me2Si)[{eta(5)C(5)H(3)(t-heptyl)}Fe(CO)](2)(mu-CO)(2) (4) was also synthesized by the same approach. The molecular structures of cis- and trans-(Me2Si)[(eta(5)-t-BuC5H3)Fe(CO)](2)(mu-CO)(2) have been determined by X-ray diffraction. (C) 1998 Elsevier Science S.A.

  In reactions of the singly bridged bis(cyclopentadiene) (SnMe2)((BuC5H4)-Bu-i)(2) (1) or the doubly bridged bis(cyclopentadienes) (SiMe2)(SnMe2)(RC5H3)(2) (R = H (2), R = Bu-t (3)) with Fe(CO)(5) in refluxing xylene, the bridging SnMe2 group migrates from the ligand to the iron atoms to give compounds (5, 7, 9a,b) containing the Fe-Sn-Fe units, together with the corresponding destannylated products (6, 8, 10a,b); the bridging SiMe2 group (in 2 and 3) does not migrate. However, in the reaction of the doubly bridged ligand (GeMe2)(SnMe2)(C5H4)(2) (4) with Fe(CO)(5), the SnMe2 group undergoes a similar migration to produce the complex GeMe2[(eta(5)-C5H4)Fe(CO)(2)](2)SnMe2 (12), containing the Fe-Sn-Fe unit, both SnMe2 and GeMe2 groups migrate from the ligand to the iron atoms to yield the product [(GeMe2)(eta(5)-C5H4)Fe(CO)(2)][(SnMe2)(eta(5)-C5H4)Fe(CO)(2)] (11), containing one Fe-Ge bond and one Fe-Sn bond, or the SnMe2 group is cleaved to afford the destannylation product GeMe2[(eta(5)-C5H4)Fe(CO)](2)(mu-CO)(2) (13). The stability of complexes 5, 7, and 12 containing the Fe-Sn-Fe unit toward heat and light was also studied. The molecular structures of 9a,b, 11, and 12 were determined by X-ray diffraction.
