A square planar iron complex with H2babp was synthesized and its coordination behaviors with monodentate axial ligands were studied. Cl– or imidazole ligand coordinated at the axial positions of the complex, but pyridine could not be introduced. The heterocyclic nitrogen donors, such as pyridine and imidazole, abstracted the amide protons of the ligand H2babp [1]. The oxidation reactivity was controlled by the presence or absence of amide protons of planar ligand H2babp rather than the axial ligands. The oxidation of cyclohexene by their complexes in the presence of PhIO proceeded catalytically when the iron complexes with protonated H2babp was used, while only a slight amount of oxidation products were obtained when the complexes with deprotonated babp2– were used.
