To improve limitations of monometallic reaction systems including catalyst deactivation and requirement of base in some metal-catalyzed reactions, a bimetallic system is considered. Bimetallic systems can often offer ways to overcome many drawbacks, based on the combination of the two individual metal properties. The synergistic effect of bimetallic system has been reported for different applications. Herein we report on the preparation of AuPd–Fe3O4 bimetallic nanoparticles by simple and fast synthetic route and the application of the nanoparticles toward practical synthesis of mono N-alkyl amines using tandem reduction of nitroarenes and reductive amination with aldehydes. Thus, the new catalyst system could offer a very sustainable, environment-friendly tool useful for potential industrial applications in the reductive amination reaction of nitro compounds.
