Abstract

In the past 5 years studies on the properties of cobalt(II) oxygen carriers¹ have afforded an excellent opportunity to attack some of the central questions regarding biological oxygen carriers. More recently, it has been found that synthetic iron(II) systems can be reversibly oxygenated,² offering further opportunities of characterizing transition metal-dioxygen interactions. We now have investigated the interaction of dioxygen with meso-tetraphenylporphyrin-(pyridine)manganese(II), Mn(TPP)(py), and report the first observations of reversible adduct formation between a manganese porphyrin and dioxygen.
