Influence of the Structure of the Macroheterocyclic Ligand on the Catalytic Properties of Metal Tetraarenoporphyrazine Complexes: I. Decomposition of Hydrogen Peroxide on Co and Fe Complexes

The catalytic activity of cobalt and iron complexes of the tetraarenoporphyrazine series in decomposition of hydrogen peroxide under heterogeneous conditions was studied. The catalytic properties of metal complexes are affected not only by the nature of the metal, but also by the peripheral structure of the macroheterocycle, varying in parallel with the electron-withdrawing power of the ligand.
