A newly prepared quaternary ammonium salt (QAS) gemini fluorosurfactants efficiently catalyze one-pot Mannich reactions of aldehydes, amines and ketones in aqueous media at ambient temperature to afford corresponding beta-aminocarbonyl compounds in good to excellent yields. In addition, the gemini fluorosurfactant catalysts were recovered and reused for three times with little loss of their catalytic activities. (C) 2007 Elsevier B.V. All rights reserved.
