Abstract : The Knoevenagel reaction is one of the most useful methods for the synthesis of α,β-unsaturated nitriles. We disclose an efficient protocol for the Knoevenagel reaction of aldehydes withmalononitrile catalyzed by 1-alkyl-1,2,4-triazolium salts to afford the corresponding products in excellentyields. The important feature of this reaction is the catalyst; 1-alkyl-1,2,4-triazolium salts are recycledand reused. Furthermore, the reaction conditions are environment friendly and do not produce anyhazardous waste.
