An Efficient Copper‐Catalyzed Amination of Aryl Halides by Aqueous Ammonia

Abstract The copper(I) bromide/1‐(5,6,7,8‐tetrahydroquinolin‐8‐yl)‐2‐methylpropan‐1‐one (CuBr‐ L3 ) combination catalyzed the cross‐coupling reactions between aryl or heteroaryl halides and aqueous ammonia with high yields to produce primary aromatic or heteroaromatic amines at room temperature or under mild conditions.
