Nitrogen-doped graphene-activated iron-oxide-based nanocatalysts for selective transfer hydrogenation of nitroarenes
Nanoscaled iron oxides on carbon were modified with nitrogen-doped graphene (NGr) and found to be excellent catalysts for the chemoselective transfer hydrogenation of nitroarenes to anilines. Under standard reaction conditions, a variety of functionalized and structurally diverse anilines, which serve as key building blocks and central intermediates for fine and bulk chemicals, were synthesized in good to excellent yields.
A facile reduction of nitroarenes to anilines using FeCl 3·6H2O/indium
Reduction of a variety of nitroaromatic compounds to the corresponding anilines occurs chemoselectively in high yields upon treatment with a new reduction system consisting of FeCl3·6H2O/indium in aqueous methanol.
