Jang, Mingyeong; Lim, Taeho; Park, Byoung Yong; Han, Min Su published an article in 2022. The article was titled 《Metal-Free, Rapid, and Highly Chemoselective Reduction of Aromatic Nitro Compounds at Room Temperature》, and you may find the article in Journal of Organic Chemistry.Formula: C5H5BrN2 The information in the text is summarized as follows:
A metal-free and highly chemoselective method for the reduction of aromatic nitro compounds, RNO2 (R = 4-BrC6H4, quinolin-6-yl, 2-methyl-1,3-benzoxazol-6-yl, etc.) has been described. This reduction was performed using tetrahydroxydiboron [B2(OH)4] as the reductant and 4,4′-bipyridine as the organocatalyst and could be completed within 5 min at room temperature Under optimal conditions, nitro compounds RNO2 with sensitive functional groups, such as vinyl, ethynyl, carbonyl, and halogen, were converted into the corresponding amines, RNH2 with excellent selectivity while avoiding the undesirable reduction of the sensitive functional groups. In the part of experimental materials, we found many familiar compounds, such as 6-Bromopyridin-3-amine(cas: 13534-97-9Formula: C5H5BrN2)
6-Bromopyridin-3-amine(cas: 13534-97-9) belongs to anime. Amines can be classified according to the nature and number of substituents on nitrogen. Aliphatic amines contain only H and alkyl substituents. Aromatic amines have the nitrogen atom connected to an aromatic ring.Important amines include amino acids, biogenic amines, trimethylamine, and aniline. Inorganic derivatives of ammonia are also called amines, such as monochloramine (NClH2).Formula: C5H5BrN2
