Catalysts For Reduction Of Aromatic Nitro Groups To Anilines

ID: 2015-041 Catalysts for reduction of aromatic nitro groups to anilines with hydrazine hydrate as reductant.


Principal Investigator: David Michaelis

This polymer-ligand approach (ruthenium-cobalt bimetallic nanoparticles supported on polystyrene) to nanoparticle catalysis provides an attractive strategy for improving catalyst reactivity and selectivity by systematically varying the electronic structure of the polymer support. These variations in polymer structure lead to predictable changes in the catalyst activity that can be used to optimize catalyst efficiency, as is accomplished through ligand design in homogeneous catalysis.

Our studies have also led to the development of readily synthesized, polymer-supported bimetallic nanoparticle catalysts that exhibit exceptional activity and chemoselectivity in nitroarene reduction reactions that occur at room temperature. These nanocomposite polymer catalysts are synthesized in a single step from commercial polymers and metal salts, enable efficient and chemoselective catalysis under mild conditions, and can be recovered and reused without loss of catalytic activity.
