Compounds in the title series have been synthesised by capping mesoporphyrin-II with protected hydroquinone derivatives, deprotection, and oxidation, followed by magnesium insertion; 1H n.m.r. spectroscopy demonstrates that the metal ion is 5-co-ordinate, bound intramolecularly to a quinone carbonyl oxygen, and can accept a sixth ligand from the unhindered side.
