Procedure
An improved process for producing triarylamines directly from an aniline is to react an arylchloride with an aniline compound in the presence of a suitable catalyst. For example, 3,4-dimethylaniline can be rapidly reacted with chlorobenzene to form 3,4-dimethyl-N,N-diphenylaniline using palladium acetate ligated with 2,4,6-trioxa-1,3,5,7-tetramethyl-8-phosphaadamantane, which is manufactured as Cytop-216 (Cytec Industries), and sodium t-pentoxide base. This reaction proceeds rapidly, in about 4 to 8 hours to produce the desired triarylamine.
