Using tripodal ligands as tools, the kinetics of iron removal from ferric complexes of the tripodal tris(hydroxyquinoline) ligands O‐TRENSOX and of tris(catechol) TRENCAMS was investigated. Two hexadentate heterotripodal ligands were also examined (TRENSOX2CAMS with two hydroxyquinoline and one catechol subunits and TRENSOXCAMS2 with two catechol and one hydroxyquinoline subunits) as possible models of the ternary complexes involved in the iron exchange process. The main result of this kinetic study is the pertinence of the iron complexes of the mixed ligands as models for the transient and successive ternary complexes occurring in the iron exchange, which proceeds “arm‐by‐arm” between a homotopic ligand and the iron complex of another homotopic ligand.
