The kinetic properties and substituent effects of the oxidns. of 17 mono- and bisporphinatoiron(III) compounds with PhIO are studied by UV-Vis. The results show that the oxidns. are second order for monoporphinatoiron(III), and first order for bisporphinatoiron(III). There are linear relationships between the reaction kinetic constant k and the substituent constant s for mono- and bisporphinatoiron(III), and the electronic effects of the substituents on the porphyrin rings on the oxidation of mono and bisporphinatoiron(III) are different.
