苄腈能发生傅克酰化反应吗?文献报道:苄腈与 溴乙酰 溴在 三氯化铝 催化下发生傅克酰化反应 具体操作步骤:The reactor was charged with 2.5 mL of 1,2-dichloroethane, AlCl3 (0.55 g, 4.14 mmol), 2-bromoacetyl bromide (1.21 g g, 6.0 mmol) was added dropwise at 0 ° C, followed by the dropwise addition of benzonitrile (0.52 g, 5.0 mmol) at one time. After the addition was complete, the cooling was stopped and stirring was continued for 4 h, the temperature was raised to room temperature, the deionized water was added to quench the excess of AlCl3, The organic layer was separated and evaporated to dryness, and the crude product was purified by column chromatography to give Compound 1-1 (0.9g, 80 percent). TLC:检测反应显示无新点产生(分别在0℃、20℃、50℃反应检测) 请教:请各位大神帮忙分析一下在该反应中不反应的原因有哪些呢?查看更多3个回答 . 15人已关注
