[PAIM][NTf]/BMIM-ILs as a base/solvent in the Corey-Chaykovsky reaction is demonstrated by the facile synthesis of libraries of functionalized cyclopropanes from enones and oxiranes from aldehydes and ketones, at room temperature in respectable isolated yields. To demonstrate their application, the synthesized epoxides were employed as substrates for the synthesis of a library of 2,3-disubstituted quinolines, using
[PAIM][NTf]/BMIM-IL 在 Corey-Chaykovsky 反应中作为碱/溶剂的潜力通过在室温下以相当高的分离度从烯酮和环氧乙烷轻松合成官能化环丙烷库来证明。产量。为了证明其应用,合成的环氧化物被用作合成 2,3-二取代喹啉库的底物,使用 [BMIM(SOH)][OTf]/[BMIM][PF] 作为催化剂/溶剂。还探讨了离子液体溶剂回收/再利用的潜力。
