The "one-pot" synthesis of triarylamines from an aniline and two different aryl halides is described. A catalytic system composed of Pd2(dba)3/P(t-Bu)2-o-biphenyl (1) is used to prepare a variety of triarylamines in a single flask by the coupling of an aniline with an aryl bromide and aryl chloride. The synthesis of triarylamines containing a heterocyclic aryl group is also described by employing a
