## Abstract The __N^2^,N^2^β²__βdiisopropyloxalohydrazide/CuO system efficiently catalyzed the direct amination of aryl bromides andiodides with aqueous ammonia in water at 60 Β°C in 24 h or at 120 Β°C in only 20β30 min. Both activated and unactivated aryl and heteroaryl bromides and iodides were read
## Abstract The easy availability of the ligand, the commercially available cheap copper source, the use of a green solvent and aqueous ammonia as the readily available nitrogen source are features of this protocol.
