Synthesis and Reactions of Novel Triply Thiolate-Bridged Diiron Complexes [Cp*Fe(μ2-SR)3FeCp*] (Cp* = η5-C5Me5; R = Et, Ph)
摘要:
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.
