四正丁基过硫酸铵在1，2二氯乙烷溶剂中可高产率地使醛和酮的2，4-二硝基苯腙衍生物氧化裂解成相应的羰基化合物，其分子中碳碳双键，氰基，酯基和缩醛基等基团均不受影响。同时探讨了可能的反应机理和反应溶剂对氧化裂解反应的影响。

2, 4- dinitrophenylhydrazone derivatives of aldehydes and ketones were converted into the corresponding carbonyl compounds in excellent yields in 1,2- dichloroethane. Other common funtioanl groups in the molecule such as olefinic double bond, cyano, ester, acetal etc were unaffacted under these reaction conditions. The possible reation mechanism and the effects of different solvent on oxidation were investigated.
