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.
提供了一种生产芳基胺的方法,其特征在于在特定吡啶盐、咪唑盐和季铵盐中选择有机盐、铜催化剂和碱的存在下,将芳香卤素化合物与芳香胺反应。因此,即使是带有电子供体基团的芳香卤素化合物的反应也可以高效地进行,可以使用廉价的氯化芳香化合物或溴化芳香化合物,并且可以以低成本生产高纯度的芳基胺,特别是三芳基胺或二芳基胺。
