Abstract

The room temperature ionic liquidsn-butyl pyridinium nitrate ([BPy]NO₃), 1-n-butyl me~thy~lim~mi~da~zo~lium tetrafluoroborate ([bmim]BF₄) and 1-n-butyl-3-methylimmidazolium hexafluorophosphate ([bmim]PF₆) were used as microwave absorbent (sensitizer) for the Knoevenagel condensation under microwave irradiation. The condensation proceeded smoothly in the presence of catalytic amount of ionic liquid toafford the desired E-isomers of the corresponding alkenes in high purity with moderate to excellent yields.

Key words: ionic liquid, Knoevenagel reaction, microwave irradiation
