摘要
研究离子液体介质中，碱催化丙二酸酯对α，β-烯酮和β-硝基烯烃的Michael加成。研究结果表明，咪唑型离子液体表现出良好的反应性能，在BMImPF6介质中，NaOH催化下，室温反应45～120min，即可得到75．2％～96．8％收率的Michael加成产物，NaOH／BMImPF6体系可以稳定地循环使用6次以上。
Based - catalyzed Michael addition of malonates to α,β-unsaturated ketones and β- nitroolefins were performed in imidazolium-type ionic liquids. In the presence of NaOH,75.2% - 96. 8% yields of Michael adducts were offered after 45 - 120min reaction at room temperature with BMImPF6 as medium. The NaOH/BMImPF6 system could be recycled and reused for at least six times without much loas in activties.
