Abstract

Abstract : A convenient method for the synthesis of magnetically recyclable palladium nanoparticles (Fe3 O4 ‐Pd) is described. The catalytic application of the Fe3 O4 ‐Pd nanoparticles was explored for the first time in oxidative coupling between amides and olefins. p ‐Toluenesulfonic acid plays a significant role in the oxidative amidation reaction. The reaction proceeds at room temperature, resulting in ( Z )‐enamides under ambient air in the absence of co‐catalyst and ligand. The superparamagnetic nature of Fe3 O4 ‐Pd facilitates easy, quantitative recovery of the catalyst from a reaction mixture, and it can be reused for up to three consecutive cycles with a slight decrease in catalytic activity.
