title: Novel ionic liquid supported on Fe3O4nanoparticles and its application as a catalyst in Mannich reaction under ultrasonic irradiation.
abstract: A family of novel ionic liquid with l-alanine and choline chloride as environmentally benign materials have been synthesized and grafted on Fe3O4nanoparticles using easy preparation techniques. The structure of ionic liquid supported on Fe3O4nanoparticles (IL-Fe3O4NPs) characterized by various analyses such as FE-SEM, EDX, XRD, NMR, FTIR and VSM. The catalytic activities of this catalyst are examined in the Mannich reaction for synthesis of β-aminocarbonyl compounds under ultrasonic irradiation. The recyclability of catalyst is investigated, and the results have indicated that the catalyst can be recycled six times without obvious activity decreasing.
