Abstract

Chemistry Chemistry, Inorganic & Nuclear Physical Sciences Science & Technology
A stopped-flow study has shown that tetrakis(pentafluorophenyl) porphyrin iron(III) chloride reacts rapidly (<3 ms) with hydrogen peroxide to form a Fe-III-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 Fe-III-H2O2 complex.
