Abstract

In this paper, rGO/Pd-Fe3O4@PPy as an efficient stable nanocomposite was synthesized. To understand the synergetic effects of rGO, Pd, Fe3O4 and PolyPyrrole, the performance of rGO/Pd-Fe3O4@PPy as a heterogeneous recyclable nanocatalyst in the green synthesis of C-C and C-O coupling products, as well as different conditions are studied. Synthesized rGO/Pd-Fe3O4@PPy was characterized by FT-IR, XRD, FE-SEM, EDS, TGA and AFM analysis. Best results are obtained under sonication in H2O for C-C coupling and by ball-milling for C-O coupling. The benefits of this method include: green solvents and conditions, absence of external base, low reaction times with high yield and easy work-up method.
