Abstract
The photoirradiation of MnIII(tpp)N3 (tpp = meso-tetraphenylporphinato) in the fluid solutions of 2-methyltetrahydrofuran at temperatures of 0 to −70 °C causes competitive reactions between the oxidation of the central manganese of the complex to yield MnV(tpp)N and the reduction to MnII(tpp). The reduction and the oxidation proceed advantageously at 25 °C and at −80 °C respectively.
