Abstract

Experimental and theoretical studies showed the differences observed in the benzylic tetrabromination reactions in 2,5-dimethylterephthalonitrile compared to 1,4-dimethylbenzene. It was observed that the compound containing the nitrile substituent underwent a slower bromination reaction, with the formation of four intermediate compounds, while for the compound without substituents, the reaction was faster and only two intermediate compounds were observed.

2,5-二甲基对苯二甲腈溴化反应与1,4-二甲基苯溴化反应动力学的实验和理论研究

摘要

实验和理论研究表明，与1,4-二甲基苯相比，在2,5-二甲基对苯二甲腈的苄基四溴化反应中观察到的差异。观察到含有腈取代基的化合物进行的溴化反应较慢，形成了四种中间体化合物，而对于没有取代基的化合物，反应更快，仅观察到两种中间体化合物。
