    • Abstract

       

      A three-component Mannich-type reaction of aromatic aldehydes, ketones, and amines was catalyzed by a novel choline-based acidic ionic liquid. The proposed catalyst was a Lewis-BrØnsted dual acid catalyst as well as water-tolerant. The β-amino carbonyl compounds were obtained at room temperature in reasonable to good yields ranging from 63 to 98%. After the reaction, the catalyst could be recycled and reused for 5 times without obvious decrease of the yield. Further, the catalyst was environment-friendly with a significant biodegradation rate.
