Article abstract of DOI:10.1246/bcsj.57.905

The reaction of 1,1-dimethyl-1-phenacylhydrazinium bromide with 1 M aqueous sodium hydroxide give benzoic acid, 3-phenyl-1-methylpyrazole, 5-benzoyl-3-phenyl-1-methylpyrazole, and benzonitrile as the major components; the expected product, 2-benzoyl-5-phenylimidazole was formed in only small amounts.Mechanisms to rationalize the formation of the major products are discussed.
