Facile, mild, and environmentally benign procedure for the cleavage of carbon-nitrogen double bonds using KMnO_4 in the presence of montmorillonite K-10 under solvent-free conditions

摘要

An efficient and environmentally benign method for the conversion of oximes, semicarbazones, phenylhydrazones, and azines to their corresponding carbonyl compounds using KMnO_4/montmorillonite K-10 as a commercially available, non-toxic, stable, and inexpensive reagent is reported.
