Brief Introduction
Aromatic amines are a kind of important nitrogen-containing compounds, which are widely used in explosives, dyes and pharmaceutical industries. The synthesis method is generally based on well-known reactions. Simple aromatic amines can be prepared by reduction of nitro compounds or by k-amino substitution of halogenated aromatics. In addition, there are other special preparation methods. in recent years, α- Naphthylamine (also known as 1-naphthylamine) has been well used in dye chemical industry and organic synthesis, especially in the synthesis of axial chiral catalysts.
