## 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
A simple and efficient methodology for the synthesis of triphenylamine (TPA) in a single step has been demonstrated using copper catalyst with a ligand. The effect of parameters such as catalyst precursors, ligands, bases and solvents on activity and selectivity to triphenylamine were studied at 115
