摘要
以辅酶Q0即2,3-二甲氧基-5-甲基-1,4-对苯二醌为原料在氯仿回流温度下,与溴等摩尔比反应,经石油醚重结晶得到6-溴-2,3-二甲氧基-5-甲基-1,4-对苯二醌。收率为97.55%。所得产物结构均经1H-NMR谱表征。
The bromization was carried out in refluxing chloroform, coenzyme Q0（2,3-dimethyoxyl-5-methyl-1,4-benzo-quinone）：Br2=1 ：1（mol：mol）,and bromine was dropwise for lhr.The crystal of 6-bromo-2,3-dimethoxy-5-methy1-1,4-benzoquinone was obtained by recrystallization in petroleum ether.The yield of bromization was 97.55%, And the products＇ structures were characterized by IH-NMR
