| 摘 要： | 利用循环伏安法研究了2-硝基苯甲醚在离子液体中的电化学还原行为。以Cu为工作电极，石墨电极为对电极，饱和甘汞电极(SCE)为参比电极，在室温离子液体中电化学还原2-硝基苯甲醚合成2-氨基苯甲醚。优化了电解实验条件，在最佳实验条件(E= -1.0 V, T=50 ℃, c=74.4 mmol·L-1, Q=6 F·mol-1, Y=10:1)下2-氨基苯甲醚的产率最高可达51.3%。在离子液体中电化学合成2-氨基苯甲醚，反应条件温和，避免了有毒易挥发的溶剂、催化剂及其他支持电解质等的使用；并实现了离子液体的重复利用，为2-氨基苯甲醚提供了一条新的绿色化合成路线。

| Abstract: | A new electrochemical synthesis of 2‐anisidine from 2‐nitroanisole has been developed in room‐temperature ionic liquid (RTIL), which was carried out under mild and safe conditions, where the volatile, toxic solvents, catalysts, as well as any additional supporting electrolyte were avoided. The maximal yield of 2‐anisidine reached 51.3% on Cu‐graphite couple electrodes under potentiostatic electrolysis at ?1.0 V (vs. SCE) until 6 F·mol?1 of charge was passed at 50 °C, which offers a new and clean route to synthesis of 2‐anisidine. The reduction behavior of 2‐nitroanisole was studied in RTIL by cycle voltammertry. The RTIL could be recycled. |
