摘要：
The reaction of 2,4-dinitrophenylhydrazine (DNPH) with model hydroperoxides has been investigated. Under conditions typically employed for carbonyl determination in oxidized polymers, the hydroperoxides undergo acid-catalyzed rearrangement to form additional carbonyl groups which subsequently react with DNPH. The rearrangement is particularly efficient for tertiary allylic hydroperoxides, although even t-butyl hydroperoxide gives some 2,4-dinitrophenylhydrazone.
