Abstract
Several chalcone phenylhydrazones and pyrazolines have been oxidized with manganese dioxide to give pyrazoles in good yields. Oxidation of p-nitrobenzylidene-o-aminophenol and m-nitrobenzylidene-m-nitrobenzylidene-o gave the corresponding benzoxazoles, whereas, substituted benzylidene-o-phenylenediamines gave the corresponding benzimidazoles.
