Abstract
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.
