| 摘要: 通过铁硫配合物(μ-RS)(μ-R'S)Fe2(CO)(R及R'=烃基、酯乙基、甲氧甲基)同三苯膦在苯或甲苯中回流数小时,分别合成了五个单三苯膦取代配合物(μ-RS)(μ-R'S)Fe2(CO)5PPh(A)和五个双三苯膦取代配合物(μ-RS)(μ-R'S)Fe2(CO)4(PPh)2(B)。除用碳氢分析、IR及1HN MR光谱鉴定了这些新配合物的结构外,还讨论了单三苯膦、双三苯膦取代反应的条件以及三苯膦对配合物光谱性质的某些影响。 |

| Abstract: Through reaction of Fe-S complexes (μ-RS) (μ-R'S)Fe2(CO)6 (R and R' = alkyl, R''OCCH2CH2, CH3OCH2) with PPh3 in boiling benzene and toluene for several hours, five mono-PPh3-substituted complexes(A), (μ-RS)(μ-R'S)Fe2(CO)5PPh3, and five bis-PPh3-substituted complexes (B),(μ-RS)(μ-R'S)Fe2(CO)4(PPh3)2, have been synthesized, respectively.For these new substituted complexes the structures have been characterized by C/H analysis, IR and 1H NMR spsctroscopy.While the reaction conditions for mono-substitution and bis-substitution have been established, some influences of ligand PPh3 towards spectroscopic properties of the complexes have also been pointed out. |
