초록/요약
A mononuclear manganese(V)–oxo complex with tetraamido macrocyclic ligand (TAML), [MnV(O)(TAML)]− (1), is a sluggish oxidant in oxidation reactions. Herein, a mononuclear manganese(V)–oxo TAML cation radical complex, [MnV(O)(TAML+.)] (2), is reported. It was synthesized by reacting [MnIII(TAML)]− with 3.0 equivalents of [RuIII(bpy)3]3+ or upon addition of one-electron oxidant to 1 and then characterized thoroughly with various spectroscopic techniques along with DFT calculations. Although 1 is a sluggish oxidant, 2 is a strong oxidant capable of activating C−H bonds of hydrocarbons (i.e., hydrogen atom transfer reaction) and transferring its oxygen atom to thioanisoles and olefins (i.e., oxygen atom transfer reaction). © 2018 Wiley-VCH Verlag GmbH & Co.
