摘要

用n -烷基咪唑与苯甲醛功能化的烷基溴化物在微波照射下季铵盐化制备了3种苯甲醛功能化离子液体,收率高。这些醛类功能化离子液体在H2O2/KOH存在下容易被氧化或被NaBH4还原生成相应的羧基功能化离子液体或苯基醇功能化离子液体。此外,还证实了这些功能化产物在还原胺化条件下与水合肼和苯胺的缩合反应。

Facile Synthesis of Benzaldehyde-Functionalized Ionic Liquids and Their Flexible Functional Group Transformations
Three benzaldehyde-functionalized ionic liquids were readily synthesized by quaternization of N-alkylimidazole with benzaldehyde-functionalized alkyl bromides under microwave irradiation in good yield. These aldehyde-functionalized ionic liquids could easily be oxidized in the presence of H2O2/KOH or be reduced by NaBH4 leading to the formation of the corresponding carboxyl-functionalized ionic liquids or benzylic alcohol-functionalized ionic liquids. In addition, the condensations of these functionalized ones with hydrazine hydrate and with aniline under reductive amination conditions were demonstrated.
