Observation of High-Valent Manganese(V)?Corrole Complexes During Metalation of meso-Functionalized A3-Corroles under Aerobic Conditions
Sprache des Titels:
We report the synthesis of alkoxy-functionalized Mn(III)?A3-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?C6 or O?C12 chains, or to +V in case of O?C18 chains. The Mn(V)?corrole displays metal-centered redox chemistry in solution. Reduction with SnCl2 or Ph3P leads to the clean conversion yielding the corresponding Mn(III) derivative.
