    摘要: 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.

    摘要: Described is a process for producing a diarylamine, which comprises subjecting an arylamine to condensation reaction in the co-presence of anhydrous aluminum chloride and anhydrous calcium chloride. The process permits the production of a diarylamine in a high yield at a normal pressure while terminating the reaction in a short time; and also permits the production, at a low cost, of a diarylamine having a high purity to be usable sufficiently as an intermediate for the production of a raw material for an electronic material.

    摘要: A method for the production of arylamine is described, which comprises allowing an aromatic amine to react with an aromatic halide in the presence of a copper-containing catalyst in a reaction solvent having an ionization potential of from 8.0 to 9.0 eV. According to the method of this invention, an arylamine, in particular a triarylamine or diarylamine, useful as a raw material for use in electronic materials or as an intermediate thereof can be produced with a high purity and in a high yield or at a low cost.
