A process for producing an arylamine is provided which is characterized by reacting an aromatic halogen compound with an aromatic amine in the presence of an organic salt selected from specific pyridinium salts, imidazolium salts and quaternary onium salts, a copper catalyst, and a base. Thus, the reaction of even an aromatic halogen compound substituted by an electron-donating group proceeds efficiently, and an inexpensive chlorinated aromatic compound or brominated aromatic compound is usable, and an arylamine, in particular a triarylamine or diarylamine, having a high purity can be produced at low cost.
A process for producing an arylamine, which comprising reacting an aromatic halogen compound represented by the following general formula (4) or (5) with an aromatic amine in the presence of at least one organic salt represented by the following general formulae (1) to (3), a copper catalyst, and a base:
