Pulse radiolysis has been used to investigate the intermediate stages of the radiolytic transformations of Mn(III)TTP in acetonitrile and the effect of oxygen upon them. It is shown that in the initial stages Mn(III)TTP reacts with the anion radicals CH3CN-· and O2-· to give the complexes Mn(III)TTP...CH3CN-· and Mn(III)TTP...O2-· respectively. Mn(II)TTP is formed with a rate constant k = (4.0 ± 0.5) × 104 sec-1 as a result of electron transfer within the complex Mn(III)TTP...CH3CN-·. The electrochemical or radiolytic reduction of Mn(III)TTP in the presence of oxygen gives the complexes Mn(II)TTP...O2, Mn(III)TTP...O2-· and Mn(IV)TTP...O22- in equilibrium with one another.
