Abstract
A task-specific ionic liquid (TSIL) has been introduced as a recyclable catalyst in Michael addition. A series of nitroalkenes and various C-based nucleophiles were reacted in the presence of 30mol% of recyclable basic-functionalized ionic liquid. Good to excellent yields were obtained in 30min under ultrasound irradiation.
摘要
一种特定于任务的离子液体（TSIL）已被引入作为迈克尔加成反应中的可回收催化剂。在存在 30mol%的可回收碱性功能化离子液体的情况下，一系列硝基烯烃和各种 C 型亲核试剂进行了反应。在超声辐射下 30min 内即可获得良好至优异的产率。
