In the presence of supported Pd nanoparticle catalysts, e.g., Pd/Al2O3, various diphenylamines could be synthesized through acceptorless formal arylation using NH3 or its surrogates, e.g., urea, as nitrogen sources and cyclohexanones as arylation sources. The observed catalysis was truly heterogeneous, and the catalyst was reusable with retention of its high catalytic performance.
A simple access to symmetric diarylamines via copper(II)-catalyzed coupling of aqueous ammonia with arylboronie acids

supporting information; experimental part, p. 708 - 709 (2011/04/22)
A simple and efficient CuII-catalyzed coupling reaction of arylboronic acids with aqueous ammonia under air is described. The reaction was conducted under atmospheric pressure and no additional ligand was required. Benzoic acid was added to tune the basicity of the reaction system. Copyright

A CuBr-catalyzed coupling reaction of hydroxylamine hydrochloride and arylboronic acids is described, providing a simple and efficient methodology for the synthesis of symmetric diaryl amines. The reaction shows good functional group tolerance. Georg Thie
Selective palladium-catalyzed arylation of ammonia: Synthesis of anilines as well as symmetrical and unsymmetrical di- and triarylamines
Surry, David S.,Buchwald, Stephen L.
, p. 10354 - 10355 (2008/03/13)
It is shown that by selection of an appropriate palladium/ligand system, temperature, concentration, and stoichiometry of reagents, ammonia may be selectively arylated to give either anilines, symmetrical di-, or triarylamines. Furthermore different aryl halides may be added sequentially to the reaction mixture, allowing the synthesis of unsymmetrical di- and triarylamines from aryl halides and ammonia in a one-pot protocol Copyright
