Reversible intramolecular electron transfer within a ruthenium(III) porphyrin-ruthenium(II) porphyrin π-cation radical system induced by changes in axial ligation
Abstract
Reaction of the octaethylporphyrinatobis(triphenylarsine)ruthenium(III) cation with CO generates the carbonyl(triphenylarsine)ruthenium(II) porphyrin π-cation radical species viaan intramolecular electron transfer; the process is quantitatively reversible.
