通过 [Cp*FeCl](2) 与 LiSEt 或 LiSPh 在 THF 中反应得到新型硫醇盐桥联二铁配合物 [Cp*Fe(mu(2)-SR)(3)FeCp*] (1, R = Et; 2, R = Ph)。在 THF 中用 CO 或 (CNBu)-Bu-t 处理 1 得到络合物 [Cp*FeSEt(mu(2)-SEt)(2)FeCp*CO] (3) 或 [Cp*FeSEt(mu(2)-SEt)(2)FeCp*(CNBu)-Bu-t] (4)，而 1 与 (CNBu)-Bu-t 在 CH2Cl2 中反应导致形成络合物[Cl2Fe(mu(2)-SEt)(2)FeCp*(CNBu)-Bu-t] (5)。这五种配合物已通过光谱和晶体学进行了表征。此外，5的形成表明此类簇可能作为碳卤键活化试剂（催化剂），并且还描述了4的碳卤键断裂反应。
The novel thiolate-bridged diiron complexes [Cp*Fe(mu(2)-SR)(3)FeCp*] (1, R = Et; 2, R = Ph) have been obtained by the reaction of [Cp*FeCl](2) with LiSEt or LiSPh in THF. Treatment of 1 with CO or (CNBu)-Bu-t in THF gives complex [Cp*FeSEt(mu(2)-SEt)(2)FeCp*CO] (3) or [Cp*FeSEt(mu(2)-SEt)(2)FeCp*(CNBu)-Bu-t] (4), while reaction of 1 with (CNBu)-Bu-t in CH2Cl2 results in the formation of complex [Cl2Fe(mu(2)-SEt)(2)FeCp*(CNBu)-Bu-t] (5). These five complexes have been spectroscopically and crystallographically characterized. In addition, the formation of 5 indicates that this class of clusters might serve as carbon-halogen bond activation reagents (catalysts), and carbon-halogen bond cleavage reaction of 4 is also described.
