  By the electrocatalytic reactions of [Fe2(CO)6(μ-pdt)] (1) (pdt = SCH2CH2CH2S) with bidentate phosphine complexes dppx (dppm = PPh2CH2PPh2, dppe = PPh2(CH2)2PPh2, dppt = PPh2(CH2)4PPh2), three mono-substituted diphosphine complexes [Fe2(CO)5(μ-pdt)(k1-dppm)] (2), ([Fe2(CO)5(μ-pdt)(k1-dppe)] (3) and [Fe2(CO)5(μ-pdt) (k1-dppt)] (4) were synthesized by keeping the controlling potential at -1.75 V. Di-substituted phosphine complexes [Fe2(CO)4(μ-pdt)(k2-dppe)] (5), [Fe2(CO)4(μ-pdt)(μ-dppm)] (6), [Fe2(CO)4(μ-pdt)(μ-dppm)] (7), [Fe2(CO)4(μ-pdt) (μ-dppt)] (8) were synthesized by holding the potential at -1.85 V. The mono-substituted diphosphine complexes 3 and 4 were characterized by elemental, NMR and IR analysis. We also discuss the catalytic mechanisms of the synthetic process.

  通过[Fe2(CO)6(μ-pdt)] (1)（pdt = S S）与二齿膦配合物dppx（dppm = PPh2 PPh2，dppe = PPh2(CH2)2PPh2，dppt = PPh2( )4PPh2）进行电催化反应，合成了三个单取代双膦配合物[Fe2(CO)5(μ-pdt)(k1-dppm)] (2)、[Fe2(CO)5(μ-pdt)(k1-dppe)] (3) 和[Fe2(CO)5(μ-pdt)(k1-dppt)] (4)，控制电位保持在-1.75 V。在保持电位为-1.85 V的情况下，合成了二取代膦配合物[Fe2(CO)4(μ-pdt)(k2-dppe)] (5)、[Fe2(CO)4(μ-pdt)(μ-dppm)] (6)、[Fe2(CO)4(μ-pdt)(μ-dppm)] (7)和[Fe2(CO)4(μ-pdt)(μ-dppt)] (8)。对单取代双膦配合物3和4进行了元素分析、NMR和IR分析表征。我们还讨论了合成过程的催化机制。

  alumina) gives [Fe2(CO)5(κ1-dppmO)(μ-pdt)] (5). With bis(dicyclohexylphosphino)methane (dcpm), heating in toluene cleanly affords [Fe2(CO)4(μ-dcpm)(μ-pdt)] (6). With Me3NO · 2H2O in MeCN the reaction is not clean as the phosphine is oxidised but monodentate [Fe2(CO)5(κ1-dcpm)(μ-pdt)] (7) can be seen spectroscopically. With 1,2-bis(diphenylphosphino)benzene (dppb) and cis-1,2-bis(diphenylphosphino)ethene

  Heating [M-2(CO)(6)mu-S(CH2)(n)S}] (M = Fe, Ru; n = 2 (edt), 3 (pdt)) with bis(diphenylphosphino)methane (dppm) in toluene affords the bridged-diphosphine complexes [M-2(CO)(4)(mu-dppm)mu-S(CH2)(n)S}]. At room temperature, all show two separate environments for the methylene protons of the diphosphine ligand, while at higher temperatures these coalesce to a single peak. This behavior, which interconverts the two sulfur atoms, is ascribed to a concerted double trigonal-twist of the M(CO)(2)P moieties. No such fluxional behavior was observed for the nonlinked dithiolate complexes [Fe-2(CO)(4)(mu-dppm)(mu-SR)(2)] (R = Me, Ph, p-tolyl). The X-ray structures of [M-2(CO)(4)(mu-dppm)(mu-edt)] (M = Fe, Ru) and [Fe-2(CO)(4)(mu-dppm)(mu-SMe)(2)] are presented in order to compare them to the previously reported [M-2(CO)(4)(mu-dppm)(mu-pdt)].
