Abstract:	Nitration of aromatic halides proceeded smoothly in the presence of catalytic amounts of Cu bronze and N,N′-dimethylethylenediamine. Sodium nitrite-18-crown-6, or tetra-n-butylammonium nitrite (n-Bu₄NNO₂) turned out to be efficient nitrating agents. The aromatic nitro compounds were synthesized under essentially neutral conditions.

Keywords:	Nitration Copper catalyst Aryl iodide Nitroarenes Nitrites
