The reaction of 3,4,5,6-tetrahydro-2H-azepin-7-ol hydrogen sulfate with nucleophilic reagents was studied. The tetrahydroazepin-7-ol hydrogen sulfate reacted with alcohols and oximes to give respectively e-caprolactam and the corresponding hydrogen sulfate of the reagents in good yields. Treatment with cyclohexylamine or benzylamine afforded e-caprolactam, the amine salt of the corresponding sulfamic
研究了 3,4,5,6-四氢-2H-azepin-7-ol 硫酸氢盐与亲核试剂的反应。四氢吖庚因-7-醇硫酸氢盐与醇和肟反应,分别得到ε-己内酰胺和相应的试剂硫酸氢盐,收率良好。用环己胺或苄胺处理得到ε-己内酰胺、相应氨基磺酸的胺盐和相应的硫酸氢四氢氮杂-7-醇胺盐,而苯氨基磺酸苯胺仅在与苯胺的反应中形成。根据这些结果,证实四氢吖庚因-7-醇硫酸氢盐通过亲核试剂对硫原子的攻击而仅经历氧-硫键的裂解。
