【摘要】 以己内酰胺和硫酸二甲酯为原料,在无溶剂条件下合成了1-氮杂-2-甲氧基-1-环庚烯,考察了反应时间、反应温度、反应物配比等对反应收率的影响。结果表明:当反应物n(己内酰胺)∶n(硫酸二甲酯)=1∶1时,80℃反应2h,反应生成1-氮杂-2-甲氧基-1-环庚烯己内酰胺的收率72.3%。更多还原

【Abstract】 1-Aza-2-methoxy-1-cyccloheptene was synthesized by reaction of caprolactam and dimethylsulfate without solvents.Effect of reaction time,reaction temperature and proportion of reactants on the yield of 1-aza-2-methoxy-1-cyccloheptene was investigated.Yield of 1-aza-2-methoxy-1-cyccloheptene reached 72.3% when the molar ratio of caprolactam to dimethylsulfate was 1∶1 and reacted at 80℃ for 2 h.更多还原
