摘要：

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