Abstract

PEG1000-based dicationic acidic ionic liquid (PEG1000-DAIL) was found to be an efficient and recyclable catalyst for Mannich-type reaction of different ketones with various aromatic aldehydes and aromatic amines in water to give various β-arylamino ketones in good yields. The catalytic system could be easily recovered and reused for at least six runs only with slight decrease in its activity.
