离子液体中α,β-不饱和化合物的绿色合成

A Green Synthesis of α,β-unsature Compounds Promoted by Ionic Liquid

摘要: 在离子液体BmimBF4介质中,通过芳醛与活泼亚甲基化合物的Knoevenagel缩合反应合成了一系列α,β-不饱和化合物.反应温度低(80℃),反应时间短(2~6 h),收率较高(58%~95%).产物经1HNMR、Mass和IR进行了结构表征.

Abstract: Knoevenagel condensation of aromatic aldehydes with methylenes proceeded very efficiently in ionic liquid.The reaction can be carried out in good yield(58%~95%) under lower temperature(80 ℃) and in a short time(2~6 h).The structures of products were characterized by 1HNMR,Mass and IR spectra.
