In solution, the self-exchange reactions for oxygen-centered pi-radicals, e.g., PhO. + PhOH PhOH + PhO., are known to occur with low activation enthalpies (E(a) approximately equal to 2 kcal/mol). For the PhO./PhOH couple and, we conclude, for other O-centered pi-radicals, exchange occurs by proton-... View More
