摘要：

The reaction of bis(2-pyridyl) disulfide with [HFe(CO)(4)](-) affords [Fe(CO)(4)(SC5H4N)](-), in which the pyridine-2-thiolate ligand is bound in a monodentate (S-bonded) mode. Oxidative addition of bis(2-pyridyl)) disulfide to [Fe(CO)(4)(SC5H4N)](-) and concomitant displacement of [SC5H4N](-) leads to the neutral monomeric compound cis-[Fe(CO)(2)(SC5H4N)(2)]. In the presence of [SC5H4N](-) in CH3CN at 60 degrees C, cis-[Fe(CO)(2)(SC5H4N)(2)] undergoes facile conversion to d(6) Fe(ll) high-spin [Fe(SC5H4N3](-). Reduction of cis-[Fe(CO)(2)(SC5H4N)(2)] and [Fe(SC5H4N)(3)](-) under CO at room temperature with [BH4](-)/[Na][benzophenone] affords the monodentate (S-bonded) complex [Fe(CO)(4)(SC5H4N)](-). The results are consistent with sulfur-donor atom stabilization of the lower oxidation states of iron, while the S,N-chelating pyridine-2-thiolate ligand enhances the stability of iron in the higher oxidation state.
