Application of 16588-26-4. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 3-Bromo-4-chloronitrobenzene, is researched, Molecular C6H3BrClNO2, CAS is 16588-26-4, about Cobalt-Catalyzed C-N Bond-Forming Reaction between Chloronitrobenzenes and Secondary Amines. Author is Toma, Gabriel; Yamaguchi, Ryohei.
Cyclic secondary amines react with mono- or dichloronitrobenzenes in the presence of a catalytic amount of cobalt(II) chloride. Phosphane ligands are beneficial for the reaction, although the bite-angle effect was not strong. The resulting nitro-substituted tertiary amines are important as bioactive compounds and can also be intermediates for the synthesis of substituted anilines. This work represents the first cobalt-catalyzed approach to C-N bond-forming reactions involving aromatic chlorides and cyclic secondary amines. The reaction is ortho- and para-selective, with meta-substituted halides being unreactive in this procedure.
