Abstract

AIM AND OBJECTIVE:

Ionic liquids are 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.

RESULTS:

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; ionic liquid; magnetic nanocatalyst; nanocomposite; poly-substituted pyrroles
