The buffer-catalyzed and uncatalyzed reactions of various alkyl hydroperoxides and hydrogen peroxide with chelated protohemin chloride have been studied. The rates of the uncatalyzed reactions show the same dependence on structure as the catalyzed reactions. The rates of reactions of peracids and hydroperoxides show similar dependencies on leaving ion stability. These and other evidence indicate that these reactions proceed by heterolytic cleavage of the oxygen-oxygen bond under the conditions employed.
