Abstract
An electrochemical study of hydroxide- and methoxide-ligated Fe(III) tetraphenylporphyrins possessing ortho-phenyl substituents that block .mu.-oxo dimer formation was carried out. Ligation by these strongly basic oxyanions promotes the formation of Fe(IV)-oxo porphyrins upon 1-electron oxidation. Further 1 electron oxidation of the latter provides the iron (IV)-oxo porphyrin .pi.-cation radical. These results are discussed in terms of chemical model studies and the enzymatic intermediate compounds I and II of the peroxidases.This publication has 12 references indexed in Scilit:
