acid for the synthesis of β-amino carbonyl derivatives. Reaction time and yield of the products depended on the nature of acetophenone and aniline subsituents. Using aliphatic amines instead of aromatic amines under same reaction conditions, afforded aldol condensation products without yielding the expected β-amino ketones. Replacing the acetophenone derivatives with rhodanine yielded 5-(4-fluoroben

Unprecedented examples of 1-alkyl-1,2,4-triazolium methanesulfonate based Brønsted acidic room temperature ionicliquids were synthesized and characterized. Their catalytic activity and efficiency in recyclability and reusability on one pot synthesis of halide substituted β-amino carbonyl compounds are reported.Graphical Abstract
