Article abstract of DOI:10.1246/cl.1992.799

Double-sided porphyrinatoiron(II) bearing covalently bound axial imidazole, 5,10,15-tris(2,6-bis(3,3-dimethylbutyryloxy)phenyl)-20-(2-(3,3-dimethylbutyryloxy)-6-(5-imidazolylvaleroyloxy)phenyl)porphyrinatoiron (1b), was synthesized: The substituents of 1b are bound with the porphyrin only through ester bonds. 1b formed a stable O2 adduct reversibly in toluene at 25 deg C or with a lipid surfactant under physiological conditions.
