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 Copper(I)-induced bromine-hydrogen exchange of 2,3-dibromoanilines, published in 1984, which mentions a compound: 16588-26-4, Name is 3-Bromo-4-chloronitrobenzene, Molecular C6H3BrClNO2, HPLC of Formula: 16588-26-4.
The Cu(I)-induced Br/H exchange reaction of 2,3-dibromoaniline and 5-substituted 2,3-dibromoanilines in the 2-position has been kinetically studied in aqueous HOAc-HCl medium at 90°. The dehalogenation reaction is 2nd order, 1st in both substrate and Cu+, and may be interpreted as a reductive substitution, composed of two 1-electron steps. The 2,3-dibromophenol was only qual. examined but gave similar results.
Compound(16588-26-4)HPLC of Formula: 16588-26-4 received a lot of attention, and I have introduced some compounds in other articles, similar to this compound(3-Bromo-4-chloronitrobenzene), if you are interested, you can check out my other related articles.
