摘 要:以2-甲基萘为原料,在甲醇为溶剂的条件下,以双氧水-氢溴酸为溴化剂,制备出了高纯度的1-溴-2-甲基萘,考察了反应条件对产品收率影响。优化反应条件为:n(2-甲基萘)∶n(氢溴酸)∶n(双氧水)= 1∶1.6∶1.6,反应温度控制在0~5℃,此条件下产品收率达到94%,产品结构经过MS和1H NMR确认。

Abstract:1-Bromo-2-methylnaphthalene was synthesized in 94% yield from 2-methylnaphthalene by oxidative bromination with hydrogen peroxide-hydrobromic acid. The optimum conditions were obtained as follows:n(2-methylnaphthalene)∶n(hydrobromic acid)∶n(hydrogen peroxide)= 1∶1.6∶1.6,reaction temperature 0~5℃. The product was characterized with MS and 1H NMR.
Key words:2-methylnaphthalene;bromination;1-bromo-2-methylnaphthalene
