    Mechanisms of antioxidant action: reactions of phosphites .

    Triphenyl phosphite by contrast reacts in a strictly stoicheiometric reaction with 1-methyl-1-phenylethyl hydroperoxide but other cyclic phosphites, ethylene isopropyl and isopropyl propane-1,3-diyl phosphites (III) and (IV), behave similarly to the o-phenylene phosphites but give different first-order rate constants in the catalytic stage of .

    MECHANiSMS OF ANTIOXIDANT ACTION. PHOSPHITE ESTERS

    The antioxidant is a powerful Lewis acid as is shown by the decomposition products formed from cumene hydroperoxide by both the catechol hindered-phenyl phosphite and phosphate (Figure 13). At low hydroperoxide to phosphite ratios the product is primarily that expected from a homolytic breakdown of hydroperoxide, namely i-methyl styrene.
