Palladium-DABCO complex supported on γ-Fe2O3 magnetic nanoparticles: A new catalyst for CC bond formation via Mizoroki⬜Heck cross-coupling reaction

⬢Palladium-DABCO complex supported on γ-Fe2O3 (Pd-DABCO-γ-Fe2O3) was synthesized.⬢Pd-DABCO-γ-Fe2O3 is a new phosphine-free palladium catalyst.⬢Pd-DABCO-γ-Fe2O3 was successfully applied in Mizoroki⬜Heck cross-coupling reaction.⬢Pd-DABCO-γ-Fe2O3 was isolated from the reaction mixture by magnetic decantation.

In this paper, palladium-DABCO complex supported on γ-Fe2O3 magnetic nanoparticles (Pd-DABCO-γ-Fe2O3) was synthesized and characterized by HRTEM, SEM, XRD, XPS, ICP, FT-IR, TGA, VSM and elemental analysis. The synthesized catalyst was successfully applied as a new magnetically recyclable heterogeneous catalyst in Mizoroki⬜Heck cross-coupling reaction of aryl halides with alkyl acrylates and styrene under solvent-free conditions.
