A high valent Mn V O porphyrin dimer is prepared by peracid oxidation of an Mn III dimer under basic conditions at room temperature (see scheme; mCPBA= m ‐chloroperbenzoic acid). The addition of an acid to a solution of the Mn V O complex results in quantitative dioxygen evolution. Water and/or hydroxide ions are the sources of both the oxo ligand and the evolved dioxygen.
