The Knoevenagel condensation of a series of aromaticaldehydes with active methylene compounds proceeds smoothly in the presence ofcatalytical amounts of the functionalized ionic liquid, 1-(2-hydroxyethyl)-3-methyl imidazolium chloride, at 80 ℃ to afford the desired alkenes in good purity and 82%~97% yields without solvent. The reaction condition is mild, neutral, and the procedure is simple.

Key words: functionalized ionic liquid, catalyze, Knoevenagel condensation
