Observation of High-Valent Manganese(V)–Corrole Complexes During Metalation of meso-Functionalized A3-Corroles under Aerobic Conditions

We report the synthesis of alkoxy-functionalized Mn(III)–A 3 -corrole and Mn(V)–corrole complexes. Depending on the length of the alkoxy chain attached to the meso -tetrafluoropenyl moiety, the oxidation state of the central manganese ion could either be tuned to +III in case of O–C 6 or O–C 12 chains, or to +V in case of O–C 18 chains. The Mn(V)–corrole displays metal-centered redox chemistry in solution. Reduction with SnCl 2 or Ph 3 P leads to the clean conversion yielding the corresponding Mn(III) derivative.
