摘 要:以離子液體—水體系為反應介質(zhì),硼氫化鉀為還原劑,二芳基甲酮還原合成了二芳基甲醇?疾炝瞬煌x子液體對反應的影響及離子液體循環(huán)使用性能。還研究了不同取代基的二芳基甲酮的還原反應過(guò)程。反應在室溫下進(jìn)行、時(shí)間短、收率高、后處理簡(jiǎn)單,且疏水性離子液體可以方便地回收和多次循環(huán)使用,對反應的效果無(wú)明顯降低,對環(huán)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 |
