The present invention relates to a production method for 4,4′-bis(alkylamino)diphenylamine, and more specifically relates to a method in which 4,4′-dinitrodiphenylamine (4,4′-DNDPA) is produced by reacting urea with nitrobenzene in the presence of a polar organic solvent and a base catalyst, and then the 4,4′-bis(alkylamino)diphenylamine (4,4′-BAADA) is produced by subjecting the 4,4′-DNDPA and a ketone to hydrogenation in the presence of a hydrogenation catalyst.

A NO‐velty: A copper(I) β‐diketiminate activates the nitrosamine Ph2NNO to give a rare, three‐coordinate copper(II) amide, [(Me2NN)CuNPh2]. Reaction of this amide with NOgas returns Ph2NNO as well as a mixed‐valence species with NO‐functionalized β‐diketiminate ligands (see scheme; Cu light blue, N dark blue, O red). Thus, both the cleavage and formation of R2NNO bonds may take place at a common

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.
