有机合成中间体

合成路线1

• 步骤: 在250mL圆底烧瓶中，加入对二甲苯1（5mL，40.78mmol）和70mL四氯化碳作为溶剂；依次加入N-溴代琥珀酰亚胺（29.86g，167.80mmol）和过氧化苯甲酰（5.83g，24.08mmol）；将反应混合物在70℃下回流12小时。
• 后处理: 反应完成后冷却至室温，过滤除去固体酰亚胺；滤液经减压蒸馏除去溶剂，得到浅黄色固体产物1,4-双(溴甲基)苯4。
• 收率: 90%
• 表征数据: 熔点142-144℃；FT-IR（KBr，cm^-1）：568（C-Br伸缩振动），1625（C=C伸缩振动）；1H NMR（300MHz，CDCl3）：4.28（s，4H，亚甲基质子），7.18（s，4H，芳香质子）。
