A marked influence on the catalytic epoxidation and hydroxylation of hydrocarbons by aqueous 30 % H 2 O 2 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).
