| Abstract: | Ionic liquids(ILs)as green solvents and catalysts have unique properties such as a broad liquid range,good solvating ability,high thermal stability,and negligible vapor pressure,especially designability of ILs,which makes the acidity of ILs can be adjustable.BPy]HSO4 andBMMIm]HSO4 acidic ILs catalyzing Claisen-Schmidt(CS) condensation of acetophenone with benzaldehyde were investigated under solvent-free conditions.The plausible mechanism was elucidated for the synthesis of chalcone using the two ILs as Brnsted acid catalysts. |
