Abstract

The N^2^,N^2^′‐diisopropyloxalohydrazide/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 20–30 min. Both activated and unactivated aryl and heteroaryl bromides and iodides were readily aminated in good to excellent yields.
