Abstract

A facile aerobic oxidation of 1,2-bis(meso-octaethylporphyrinyl)ethane and other similar dimers to the corresponding trans-1,2-bis(meso-porphyrinyl)ethenes in several organic acids has been studied by UV-vis and 1H NMR spectroscopy and the general mechanism of the oxidation has been proposed. The key step of the oxidation is monoprotonation of the two porphyrin rings in dimer followed by two electron oxidation.
