It has been established that the amount of tetralin, cumene and t-butyl hydroperoxide decomposed during the initial stages of the reaction (ΔROOH), referred to the initial concentration of dithiophosphate(Do) increases with decreasing Do. This effect can be explained by the conversion of Do to SO2 in the presence of excess ROOH, which leads to the heterolytic decomposition of the hydroperoxide.
