The term nitroaniline in chemistry refers to a derivative of aniline (C 6 H 5 NH 2) containing a nitro group (—NO 2) There are three simple nitroanilines of formula C 6 H 4 (NH 2)(NO 2) which differ only in the position of the nitro group: 2-Nitroaniline; 3-Nitroaniline; 4-Nitroaniline
2-Methoxy-4-nitroaniline is an organic compound with the formula O 2 NC 6 H 3 (OCH 3)NH 2. [2] It is one of four isomers of methoxynitroaniline. The compound is a precursor to the commercial Pigment Yellow 74 .
4-Nitroaniline, p-nitroaniline or 1-amino-4-nitrobenzene is an organic compound with the formula C 6 H 6 N 2 O 2. A yellow solid, it is one of three isomers of nitroaniline. It is an intermediate in the production of dyes, antioxidants, pharmaceuticals, gasoline, gum inhibitors, poultry medicines, and as a corrosion inhibitor. [3]
In contrast, 2-methyl-1,4-dinitrobenzene (2c) is isolated in only 9.9% yield. [4] As witnessed in the above example, when a π-acceptor substituent (πAS) is meta to a π-donor substituent (πDS), the electrophilic aromatic nitration occurs ortho to the πAS rather than para.
