Three different synthetic methods have been developed for the triarylamine: (1) non-metal catalyzed amination reaction;(2) Ullmann reaction which can be divided to traditional Ullmann reaction using excess copper as catalyst, using phase-transition-catalyst as auxiliary and post-Ullmann reaction using ligand;(3) Buchwald-Hartwig reaction catalyzed by palladium complexes. The key issue for the activity of this reaction is the structure of ligand. There are three types ligand: chelate diphosphine ligand, monophosphine ligand and non-phosphine ligand. This review is focused on the recent progress of the synthesis methods of triarylamine.

Key words: triarylamine, progress, synthetic method, palladium-catalyzed, copper-catalyzed
