Ligand control in the photochemical generation of high-valent porphyrin-iron–oxo derivatives

Abstract

Visible-light irradiation of photo-labile bromate porphyrin-iron(III) salts gave iron(IV)-oxo porphyrin radical cations (compound I model) or the neutral iron(IV)-oxo porphyrin (compound II model), depending on the electronic structure of porphyrin ligands.
