摘要
在水溶液中,用NaBrO3和HBr与强碱离子交换树脂反应,制备了具有良好稳定性的载溴树脂,该树脂于室温下,在CH3OH和CH2Cl2溶液中,在CaCO3存在下,有效地溴化芳胺为溴代芳胺化合物,得到较好的产率,同时探讨了甲醇在反应中的作用.
The bromine - supported resin was prepared by sodium bromate and hydrobromic acid reacting with strong basic resin in water. The aromatic amines were bromized to give bromo- substituted aromatic amines using the bromine - supported resin in dichloromethane - methanol containing calcium carhonate powder at room tempture, and it gave a good yields. The effect of methanol in the reaction was also discussed.
