Hemoglobin structure and function

A marked influence on the catalytic epoxidation and hydroxylation of hydrocarbons by aqueous 30 % H2O2 in an aprotic solvent and on the formation of oxoiron(IV) porphyrin intermediates in m-chloroperoxybenzoic acid (m-CPBA) reactions in polar solvent is shown by the anionic axial ligands of an electron-deficient iron(III) porphyrin complex [Fe(tpfpp)X] (tpfpp=meso-tetrakis(pentafluorophenyl)porphinato dianion; see scheme).
