A mononuclear non-heme Mn(III)-aqua complex, [(dpaq)MnIII(OH2)]2+ (1, dpaq = 2-[bis(pyridin-2-ylmethyl)]amino-N-quinolin-8-yl-acetamidate), is capable of conducting hydrogen atom transfer (HAT) reactions much more efficiently than the corresponding Mn(III)-hydroxo complex, [(dpaq)MnIII(OH)]+ (2); the high reactivity of 1 results from the positive one-electron reduction potential of 1 (Ered vs SCE = 1.03 V), compared to that of 2 (Ered vs SCE = -0.1 V). The HAT mechanism of 1 varies between electron transfer followed by proton transfer and one-step concerted proton-coupled electron transfer, depending on the one-electron oxidation potentials of substrates. To the best of our knowledge, this is the first example showing that metal(III)-aqua complex can be an effective H-atom abstraction reagent.
Direct detection of the radical cation of 2,6-di-tert-butyl-4-methylphenol generated by electron-transfer oxidation with matrix alkyl halide cation radicals. A low-temperature EPR and UV-VIS optical absorption study

Electron-transfer oxidation of 2,6-di-tert-butyl-4-methylphenol (ArOH, 1) by matrix (RHal) radical cations (RHal = Freon-113, BusCl and BuiCl) results in the formation of the radical cation ArOH?+ (2) as a primary intermed
