Pre-steady state reactivity of 5,10,15,20-tetrakis(pentafluorophenyl)-21H,23H-porphyrin iron(iii) chloride with hydrogen peroxide

Abstract

A stopped-flow study has shown that tetrakis(pentafluoro-phenyl)porphyrin iron(III) chloride reacts rapidly (<3 ms) with hydrogen peroxide to form a FeIII–H2O2 complex where log K = 2.39. This subsequently undergoes rapid intramolecular conversion (k = 4.4 s−1) to an iron(IV) intermediate, which in turn reacts with hydrogen peroxide (k′ = 54.3 M−1 s−1) to reform the original FeIII–H2O2 complex.
