通过适当选择 E 和 E'，在 Cp(CO)Fe (EEt3) (py) 与 Et3E'H 的反应中合成了具有两种不同 14 族元素配体 Cp(CO)FeH(EEt3) (E'Et-3) (E, E' = Si, Ge, Sn) 的铁 (IV) 配合物。 14族元素配体的系统配体交换实验表明，甲硅烷基和氢配体比甲锗基和氢配体更容易发生还原消除，并且在60℃下24小时，Fe-Sn键没有转化为Fe-Si或Fe-Ge键。
Iron(IV) complexes with two different group 14 element ligands, Cp(CO)FeH(EEt3) (E'Et-3) (E, E' = Si, Ge, Sn), were synthesized in the reaction of Cp(CO)Fe (EEt3) (py) with Et3E'H through all appropriate selection of E and E'. Systematic ligand exchange experiments of the group 14 element ligand revealed that the reductive elimination of Silyl and hydrido ligands occurs more readily than that of germyl and hydrido ligands, and the Fe-Sn bond was not converted into an Fe-Si or Fe-Ge bond at 60 degrees C for 24 h.
