摘要:

设计以苯胺为原料,经Friedel-Crafts酰基化反应制备对氨基苯乙酮,替代以苯为原料制备苯乙酮的实验。替代后不仅提高了实验的安全性,而且还能培养学生连续多步骤合成目标产物的实验能力,引导学生思考氨基保护在合成中的应用,有利于对学生进行科学方法和科学思维的训练。

关键词: Friedel-Crafts酰基化反应, 苯胺, 苯乙酮

Abstract:

An experiment was designed to replace benzene with aniline as the raw material in the preparation of p-aminoacetophenone by Friedel-Crafts acylation. In addition to the safety benefits, this modification challenges the students' ability to continuously synthesize the target product in multiple steps; encourages the students to think about the application of amino protection during synthesis; promotes the use of scientific methods and thinking.

Key words: Friedel-Crafts acylation, Aniline, Acetophenone
