Abstract: The reaction HFe2Co(CO)(μ3-S) with CpW(CO)3Cl has been carried out to give heterometallic carbonyl sulfido clusters Cp*WFeCo(CO)3(μ3-S) (Cp*=C5H5, Ⅰ-a; Cp*=C5H5, Ⅰ-b) and (Cp*W)2Fe(CO)7(μ3-S) (Cp*=C5H4CH3, Ⅱ-a; Cp*=C5H4CH3, Ⅱ-b) by electrophilic addition-elimination reaction. These clusters were characterized by elemental analyses, IR and 1H/ 13C-NMR. The proposal concerning reaction mechanism was discussed herewith and the structure of Ⅰ-a was determined by X-ray diffraction. |
