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>.
