摘要： 通过对甲基苯乙炔基溴化镁断裂μ-S2Fe2(CO)6的S—S键可得“开式”中间体(μ-p-CH3C6H4C≡CS)(μ-BrMgS)Fe2(CO)6。该中间体与有机卤化物作用生成了11种通式为(μ-p-CH3C6H4C≡CS)(μ-RS)Fe2(CO)6的“开式”铁硫原子簇配合物。还确定了某些配合物可能的构象体及其含量比。

Abstract: It has been found that alkynyl Grignard reagent p-CH3C6H4C=CMgBr cleaves the S-Sbond of μ-S2Fe2(CO)6 to give an "open" type of intermediates (μ-p-CH3C6H4C=CS)(μ-XMgS)Fe2(CO)6. The intermediates further react with various organic halides to yield eleven new "open" Fe-Sclusters with the general formula (μ-p-CH3C6H4C=CS)(μ-RS)Fe2(CO)6. The structures of all the complexes were characterized by IR, 1H NMR, 13CNMRand elemental analysis. According to chemical shifts and integrated values of related signals of 1H NMRthe possible isomers and the isomer ratios of some clusters have been determined.
