Benzylation and hydroalkylation of 1,3-dicarbonyl compounds using Amberlyst-15 immobilized in ionic liquid [Bmim][PF6] as an efficient reusable reagent was studied. The reagent was compared with other solid acid reagents along with role of the ionic liquid. The effect of various reaction parameters like type of reagent, solvent, substrate molar ratio, reaction time, and temperature were studied. Present
以固定在离子液体[Bmim] [PF 6 ]中的Amberlyst-15为有效的可重复使用试剂,研究了1,3-二羰基化合物的苯甲酸酯化和加氢烷基化。将该试剂与其他固体酸试剂以及离子液体的作用进行了比较。研究了试剂类型,溶剂,底物摩尔比,反应时间和温度等各种反应参数的影响。由于易于处理试剂,简单的后处理程序,经济和环境友好的方法,因此本方案是有利的。获得的产品具有良好的优良收率,并适用于多种基材。
