The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《Metal-Free Reduction of Aromatic Nitro Compounds to Aromatic Amines with B2pin2 in Isopropanol》. Authors are Lu, Hongtao; Geng, Zhiyue; Li, Jingya; Zou, Dapeng; Wu, Yusheng; Wu, Yangjie.The article about the compound:3-Bromo-4-chloronitrobenzenecas:16588-26-4,SMILESS:BrC1=C(C=CC(=C1)[N+](=O)[O-])Cl).Safety of 3-Bromo-4-chloronitrobenzene. Through the article, more information about this compound (cas:16588-26-4) is conveyed.
A metal-free reduction of aromatic nitro compounds to the corresponding amines has been achieved by a combination of B2pin2 and KOtBu in isopropanol. A series of nitro compounds containing various reducible functional groups were chemoselectively reduced in good to excellent yields.
