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.
1,1-二甲基-1-苯甲酰肼溴化物与1M氢氧化钠水溶液反应得到苯甲酸、3-苯基-1-甲基吡唑、5-苯甲酰基-3-苯基-1-甲基吡唑和苯甲腈作为主要成分;预期的产物 2-苯甲酰基-5-苯基咪唑仅生成少量。讨论了使主要产品形成合理化的机制。
