In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Continuous Flow Nucleophilic Aromatic Substitution with Dimethylamine Generated in Situ by Decomposition of DMF, published in 2013-04-19, which mentions a compound: 16588-26-4, Name is 3-Bromo-4-chloronitrobenzene, Molecular C6H3BrClNO2, Quality Control of 3-Bromo-4-chloronitrobenzene.
A safe, practical, and scalable continuous flow protocol for the in situ generation of dimethylamine from DMF followed by nucleophilic aromatic substitution of a broad range of aromatic and heteroaromatic halides is reported.
In addition to the literature in the link below, there is a lot of literature about this compound(3-Bromo-4-chloronitrobenzene)Quality Control of 3-Bromo-4-chloronitrobenzene, illustrating the importance and wide applicability of this compound(16588-26-4).
