- Process for producing arylamine
-
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.

- Polyaromatic amines. Part 2. Synthesis of 4,4′,4″-tris(N-aryl-N-phenylamino)triphenylamine, N,N-bis[4-(N-aryl-N-phenylamino)-phenyl]tolylamine and N,N,N′,N′-tetraaryl-o-phenylenediamine derivatives
-
The title compounds were synthesised and characterised as part of a study into new aromatic amines for charge transporting materials. Proton and carbon spectral data for compounds 1-6 were obtained in C6D6 as a consequence of their facile oxidation in CDCl3. Each compound was characterised by cyclic voltammetry. An estimate of the intramolecular charge mobility was deduced from the difference between the first and second oxidation potentials.

- Palladium-catalyzed synthesis of triarylamines from aryl halides and diarylamines
-
Various triarylamines can be readily prepared in excellent yields by palladium-catalyzed cross-coupling reaction of aryl halides and diarylamines. The amination reaction takes place rapidly by using the catalyst combination of Pd(OAc)2 and a bulky and electron-rich ligands, P(t-Bu)3.
