Efficient Reduction of C–N Multiple Bonds Catalyzed by Magnetically Retrievable Magnetite Nanoparticles with Sodium Borohydride

Abstract

A simple, rapid and efficient methodology has been developed for the reductive transformation of the compounds bearing C–N multiple bonds such as oximes and nitriles to the corresponding amines by sodium borohydride catalyzed by highly active solid Fe3O4 nanoparticles. The catalyst was easily recovered using external magnet and reused five times without losing its catalytic activity. A simple, rapid, efficient and reusable heterogeneous catalytic system has been developed for the reductive transformation of oximes and nitriles into corresponding amines by sodium borohydride in presence of Fe3O4 nanoparticles.
