    • Abstract

       

      The Knoevenagel condensation of aromatic aldehydes with active methylene is an efficient reaction for carbon-carbon double bond formation. A rapid, efficient, and ecofriendly protocol for the Knoevenagel condensation of active methylene compounds with aldehydes has been developed with diethylamine functionalized polyethylene glycol-600 (PEG-600) as catalyst with good to excellent yields at room temperature without solvent.
