| Summary: | In this study, a novel and environmental strategy is reported for multicomponent synthesis of pyrrole derivatives in water. We prepare and characterize Fe3O4@CTAB-SDS@Cu2+-Ag+ as a double surfactant-modified magnetic nanocatalyst. We compare catalytic activity of this catalyst with a mono surfactant-modified catalyst in the synthesis of pyrroles. It seems that the addition of Sodium dodecyl sulfate (SDS) as cosurfactant provides better stabilization of the emulsion and leads to the production of adhesive emulsions by the formation of a bilayer. On the other hand, surface decoration of SDS by Cu2+ and Ag+ improves catalytic activity. The magnetic nanocomposite was characterized by TEM, EDS, XRD, VSM and FT-IR techniques and the structure of the synthesized pyrrole was confirmed by FT-IR, 1H NMR and 13C NMR.
