Recent developments in manganese corrole chemistry

Among metallocorroles, manganese corrole chemistry is one that has flourished prominently in recent years. Numerous manganese corroles have been reported in which the oxidation state of the central manganese ranges from +3 to +6. Manganese(III) corroles are the most common form of stable Mn-corrole complexes. High-valent manganese corroles exhibit quite different spectroscopic and electrochemical properties compared with manganese(III) corroles. (Imido)manganese(V) and (nitrido)manganese(V) corroles are stable enough to be well characterized by spectroscopy. (Oxo)manganese(V) corroles may be prepared by chemical or laser flash photolysis methods, and are important mechanistic probes for oxygen atom transfer reactions in the catalytic oxidation of alkenes. While various (oxo)manganese complexes have been synthesized and extensively studied, the factors controlling their reactivity are not completely understood, suggesting that manganese corrole-mediated oxidation reactions have room for further exploration. In this review, recent advances in the field of manganese corroles are summarized.
