ABSTRACT:
A method for producing aromatic amino compound (V):by synthesizing intermediate compound (IV):by the reaction of compound (I): H2N—R1with a mixture of halogenated aryl compounds (II): Ar1—X and (III): Ar2—X in the presence of a noble metal catalyst, followed by eliminating the substituent R1from the nitrogen atom in compound (IV) under an acidic condition or an alkaline condition or by addition of a reducing agent or an oxidizing agent. (R1: a substituent having 2 to 50 carbon atoms; Ar1and Ar2: a substituted or unsubstituted hydrocarbon group or heterocyclic group having 6 to 50 carbon atoms and the same with or different from each other; and X: a halogen group). The aromatic amino compound useful as the charge transporting material can be produced efficiently at a great yield without using highly toxic raw materials.
