Novel "task-specific" deep eutectic solvents (DESs) were synthesized and were used in the Beckmann rearrangement reaction to prepare ε-caprolactam, with DES [InCl][AA] achieving 100% cyclohexanone oxime (CHO) conversion and 99.5% ε-caprolactam (CPL) selectivity under 80 °C for 2 h. This "task-specific" approach gives some advantages to the reaction, such as rapid reaction speed, high yield of the target product, easy catalyst recovery, and good universality, making the DES catalytic system of great academic significance and have potential application prospects.

合成了新型“特定任务”型低共熔溶剂（DESs），并将其用于贝克曼重排反应以制备ε-己内酰胺，其中DES [InCl][AA]在80℃下反应2小时，环己酮肟（CHO）转化率达到100%，ε-己内酰胺（CPL）选择性达到99.5%。这种“特定任务”方法赋予了该反应一些优势，如反应速度快、目标产物收率高、催化剂易于回收且通用性好，使得DES催化体系具有重大的学术意义和潜在的应用前景。
