Abstract
| - Reaction of [Cp*FeCl]2 with LiSEt and LiSPh produces the thiolate-bridged diiron complexes [Cp*Fe(μ2-SR)3FeCp*] (1, R = Et; 2, R = Ph). Treatment of 1 with CO or CNtBu in THF gives [Cp*FeSEt(μ2-SEt)2FeCp*CO] (3) and [Cp*FeSEt(μ2-SEt)2FeCp*CNtBu] (4), while reaction of 1 with CNtBu in CH2Cl2 gives [Cl2Fe(μ2-SEt)2FeCp*CNtBu] (5). Complex 4 was found to activate the C−Cl bonds of some chlorohydrocarbons under mild conditions.
- The novel thiolate-bridged diiron complexes [Cp*Fe(μ2-SR)3FeCp*] (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 CNtBu in THF gives complex [Cp*FeSEt(μ2-SEt)2FeCp*CO] (3) or [Cp*FeSEt(μ2-SEt)2FeCp*CNtBu] (4), while reaction of 1 with CNtBu in CH2Cl2 results in the formation of complex [Cl2Fe(μ2-SEt)2FeCp*CNtBu] (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.
