Research Progress in Preparation of Aromatic Amine via Reduction of Aromatic Nitro Compounds

The research progress in preparing aromatic amines via the reduction of aromatic nitro compounds is reviewed. It is pointed out that the main preparation methods include catalytic hydrogenation reduction, reduction with CO/H2O, reduction with metal, reduction with sulfide, reduction with metal hydride, electro-chemical reduction and photo-chemical reduction. Of these methods, reduction with hydrogen and reduction with hydration hydrazine, both belonging to catalytic hydrogenation, are environmentally friendly and have a high yield and good selectivity, showing promising prospect of application.
