Résumé

Arylation

Ammonia

Catalysis

Copper

Pyridyldiketone

Catalytic systems based on copper and simple ligands of ambidentate pyridyldiketone type were used in direct amination of aryl iodides and bromides with aqueous ammonia in one of the mildest conditions described in the literature, with reaction temperature ranging between 25 and 80 °C.
