摘 要:以离子液体—水体系为反应介质,硼氢化钾为还原剂,二芳基甲酮还原合成了二芳基甲醇。考察了不同离子液体对反应的影响及离子液体循环使用性能。还研究了不同取代基的二芳基甲酮的还原反应过程。反应在室温下进行、时间短、收率高、后处理简单,且疏水性离子液体可以方便地回收和多次循环使用,对反应的效果无明显降低,对环境友好。 |

Abstract:The preparation of diary methanols by reduction of diaryl ketones in ionic liquid BPy[PF6]-H2O system was described. Various kinds of ionic liquids and their recycling were investigated. The reaction was carried out at room temperature with a simple work-up procedure. Ionic liquids could be reused after removal of water under reduced pressure. |
Key words:diary ketones;reducation;hydrophobic ionic liquid;diary methanol |
