摘 要:由對羥基苯乙酮和2-溴-2-甲基丙酰胺經(jīng)Williamson醚化反應、Smiles重排反應和水解反應合成了對氨基苯乙酮。通過(guò)考察反應溶劑、重排反應溫度和物料比對反應收率的影響,確定了優(yōu)化工藝條件為:N,N-二甲基乙酰胺為溶劑、重排反應溫度控制在45~50℃、n(對羥基苯乙酮)∶n(2-溴-2-甲基丙酰胺)=1∶3。最終產(chǎn)品收率達52.1%。目標化合物的結構經(jīng)1H NMR和IR確證。 |

Abstract:4-Aminoacetophenone was synthesized from 4-hydroxyacetophenone and 2-bromo-2-methylpropanamide via Williamson etherification,Smiles rearrangement and hydrolysis reactions. Best result with 52.1% yield was obtained under conditions of reaction dissolvent of DMA,reaction temperature of 45℃~50℃ in rearrangement reaction,molar ratio of 4-hydroxyacetophenone to 2-bromo-2-methylpropanamide of 1 to 3. The structure of the title compound was confirmed by 1H NMR and IR. |
Key words:synthesis;4-hydroxyacetophenone;4-aminoacetophenone;smiles rearrangement |
