- Selective one-pot synthesis of symmetrical and unsymmetrical di- and triarylamines with a ligandless copper catalytic system
-
The one-pot synthesis of symmetrical or unsymmetrical di- or triarylamines using aryl iodides or bromides and LiNH2 as ammonia source is reported. This highly selective method is based, for the first time, on a copper-catalyzed system, which does not require the presence of any additional ligand.

- Selective palladium-catalyzed arylation of ammonia: Synthesis of anilines as well as symmetrical and unsymmetrical di- and triarylamines
-
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
