Electron-transfer properties of a nonheme manganese(iv)–oxo complex acting as a stronger one-electron oxidant than the iron(iv)–oxo analogue

Abstract

Electron-transfer properties of a nonheme Mn(IV)-oxo complex, [(Bn-TPEN)Mn(IV)(O)](2+), reveals that Mn(IV)-oxo complex acts as a stronger one-electron oxidant than the Fe(IV)-oxo analogue. As a result, an electron transfer process in N-dealkylation has been detected by a transient radical cation intermediate, para-Me-DMA˙(+), in the oxidation of para-Me-DMA by [(Bn-TPEN)Mn(IV)(O)](2+).
