Abstract
The main reduction methods of nitro-compounds to prepare amino-compounds were reviewed. 5-Amino-1,10-phenanthroline was synthesized by reduction of 5-nitro-1,10-phenanthroline with three different reduction systems, tin dichloride-hydrochloric acid, iron powder-sulfuric acid and 5% Pd/C-hydrazine hydrate, respectively. The results showed that the reduction system of 5% Pd/C and hydrazine hydrate had the better reduction effect.
