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

Sodium tetrakis(3,5-trifluoromethylphenyl) borate [NaBAr4F] efficiently catalyzed the one-pot, three-component Mannich reaction of ketones with aromatic aldehydes and different anilines in water at an ambient temperature and afforded the corresponding beta-amino carbonyl compounds in good to excellent yields.

ketones, aromatic aldehydes, and aromaticamines catalyzed efficiently by γ-Al2O3/MeSO3H (alumina/methanesulfonic acid: AMA) as a heterogeneous catalyst, which were carried out in EtOH at ambient temperature to afford the corresponding β-amino ketones in good yields and high stereoselectivities in favor of the anti isomer, was described for the first time. It was found that this catalyst could be completely
