Fe3O4@HcdMeen-Pd(0) Organic–Inorganic Hybrid: As a Novel Heterogeneous Nanocatalyst for Chemo and Homoselective Heck C–C Cross-Coupling Synthesis of Butyl Cinnamates

Abstract

Methyl-2-(1-methyl-2′-amino-ethane)amino-1-cyclopentenedithiocarbo-xylate was supported on the modified Fe3O4 MNPs. Afterwards, Pd(OAc)2 was immobilized on the modified MNPs and, then, the nanoparticles were analyzed using FT-IR, XRD, EDS, ICP-OSE, SEM, TGA and VSM spectroscopy. The catalytic efficiency of the prepared heterogeneous Pd-NPs was successfully examined in “Heck cross coupling reaction”, involving the reaction of butyl acrylate with various aryl halides in water. The advantages of this strategy include, easy recovery and efficient reusability of the expensive Pd-NPs, obtaining high yields of the butyl cinnamate cross-coupled products, short reaction times, and being performed in water for a wide range of substrates. A novel HcdMeen-Pd(0) complex was synthesized on the surface of modified Fe3O4 MNPs and fully characterized by FT-IR, XRD, EDS, ICP-OSE, SEM, TGA and VSM spectroscopy analysis. The obtained complex was then used for Chemo And Homoselective Heck C–C cross-coupling synthesis of butyl cinnamates with in water as green solvent.
