Palladium nanoparticles supported on agarose-functionalized magnetic nanoparticles of Fe3O4 as a recyclable catalyst for C-C bond formation via Suzuki-Miyaura, Heck-Mizoroki and Sonogashira-Hagihara coupling reactions

In this paper, the preparation of palladium nanoparticles supported on agarose-functionalized magnetic nanoparticles of Fe3O4 is described. The new material was characterized by EDX, TEM, TGA, FT-IR, VSM, AAS, and solid UV-visible analysis. This magnetic material has been successfully applied as a highly efficient, magnetically recoverable and air-stable catalyst for the Suzuki-Miyaura, Heck-Mizoroki and Sonogashira-Hagihara coupling reactions. Using this material as a catalyst, a wide range of substrates was employed for carbon-carbon bond formation in wet PEG 200.
