Generation of an Isolable, Monomeric Manganese(V)–Oxo Complex from O<sub>2</sub> and Visible Light Katharine A. Prokop David P. Goldberg 10.1021/ja300888t.s001 https://acs.figshare.com/articles/journal_contribution/Generation_of_an_Isolable_Monomeric_Manganese_V_Oxo_Complex_from_O_sub_2_sub_and_Visible_Light/2522248 The direct conversion of a Mn<sup>III</sup> complex [(TBP<sub>8</sub>Cz)­Mn<sup>III</sup> (<b>1</b>)] to a Mn<sup>V</sup>–oxo complex [(TBP<sub>8</sub>Cz)­Mn<sup>V</sup>(O) (<b>2</b>)] with O<sub>2</sub> and visible light is reported. Complex <b>1</b> is also shown to function as an active photocatalyst for the oxidation of PPh<sub>3</sub> to OPPh<sub>3</sub>. Mechanistic studies indicate that the photogeneration of <b>2</b> does not involve singlet oxygen but rather likely occurs via a free-radical mechanism upon photoactivation of <b>1</b>. 2012-05-16 00:00:00 LightThe generation Monomeric Manganese Complex Isolable photogeneration conversion photoactivation mechanism MnIII photocatalyst function oxidation OPPh 3.
