Iron(IV) complexes with two different group 14 element ligands, Cp(CO)FeH(EEt3)(E′Et3) (E, E′ = Si, Ge, Sn), were synthesized in the reaction of Cp(CO)Fe(EEt3)(py) with Et3E′H through an 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 °C for 24 h.
