Furaldehyde-based magnetic supported palladium nanoparticles as an efficient heterogeneous catalyst for Mizoroki–Heck cross-coupling reaction

Abstract

A novel palladium functionalised magnetic nanocatalyst (Fe₃O₄@SiO₂–FA–Pd) was prepared using silica-coated iron oxide and furaldehyde Schiff base as a supported material. FT-IR, VSM, TEM, FESEM, XPS, EDAX and TGA were used to analyse the morphological structure and chemical composition of Fe₃O₄@SiO₂–FA–Pd NPs. Thus, the prepared Fe₃O₄@SiO₂–FA–Pd NPs as a magnetic nanocatalyst were used in the Mizoroki–Heck reaction of arylbromide and terminal alkenes, exhibiting effective catalysis with good yields. The magnetic nanocatalyst can be reused up to 6 times without significantly losing catalytic activity and is easily separable from the reaction mixture. This new catalytic system has significant and potentially useful applications in the pharmaceutical industry.
