Derivatives of carbonyl compounds such as oximes, phenylhydrazones, semicarbazones and thiosemicarba-zones are used not only for the characterization and purification of carbonyl compounds[1,2] but also play an important role in the protection carbonyl compounds, as they are highly crystalline and stable compounds. Thus, the regeneration of carbonyl compounds from their derivatives under mild condition is important process in organic synthetic chemistry.We report classical method for the cleavage of oximes, phenylhydrazones, semicarbazones and thiosemicarbazones aldehydes and ketones.
