The oxidation of diphenylhydroxylamine by benzoyl peroxide
In the presence of a large excess of diphenylhydroxylamine the title reaction gives benzoic acid and diphenyl nitroxide according to the equation 2Ph2NOH +(PhCO2)2→ 2Ph2NO·+ 2PhCO2H. The reaction is of the first order in both peroxide and hydroxylamine. Although this is one of the most clear-cut examples of molecule-induced homolysis known, no convincing evidence has been adduced in favour of any one mechanism. Substituent and isotope effects are consistent with an initial electron transfer from hydroxylamine to peroxide.
