Abstract

Aims and Objective: Ionic liquids are a suitable medium for stabilization and preparation of catalytic systems.

Materials and Methods: The two-dimensional (2D) ZnO/Fe3O4 nanocomposites were synthesized using ionic liquid [OMIM]Br as a stabilizer and soft template. The nanocomposites were characterized via FTIR, XRD, VSM and SEM analysis.

Result: The catalytic activity of these composites was evaluated using a multicomponent reaction of primary amines, acetylacetone, and 2-bromoacetophenone.

Conclusion: 2D ZnO/Fe3O4 as a recyclable and green catalyst showed excellent catalytic performance for the preparation of poly-substituted pyrroles.

Keywords: Green chemistry, magnetic nanocatalyst, ionic liquid, nanocomposite, poly-substituted pyrroles, ionic liquid.
