o-Toluidine is produced industrially by nitration of toluene to give a mixture of nitrotoluenes, favoring the ortho isomer. This mixture is separated by distillation. 2-Nitrotoluene is hydrogenated to give o-toluidine. [2] The conversion of o-toluidine to the diazonium salt gives access to the 2-bromo, 2-cyano-, and 2-chlorotoluene derivatives.
3-Nitrotoluene or meta-nitrotoluene is an organic compound with the formula CH 3 C 6 H 4 NO 2. It is one of three isomers of nitrotoluene. A yellow liquid, it is used in the manufacture of meta-toluidine, which is an intermediate in the production of various dyes. [3]

Together with other isomers, 4-nitrotoluene is prepared by nitration of toluene, [4] commonly using titanium(IV) nitrate. [5] It undergoes the reactions typical for nitrobenzene derivatives, e.g. hydrogenation gives p-toluidine. Oxidation of the methyl substituent of 4-nitrotoluene has been extensively investigated.
The reaction mechanism [8] of the Bartoli indole synthesis is illustrated below using o-nitrotoluene (1) and propenyl Grignard (2) to form 3,7-dimethylindole (13). The mechanism of the Bartoli indole synthesis. The mechanism begins by the addition of the Grignard reagent (2) onto the nitroarene (1) to form intermediate 3.
Mononitrotoluene or nitrotoluene (MNT or NT), is any of three organic compounds with the formula C 6 H 4 (CH 3)(NO 2). [1] They can be viewed as nitro derivatives of toluene or as methylated derivatives of nitrobenzene. Mononitrotoluene comes in three isomers, differing by the relative position of the methyl and nitro groups. All are pale ...
2-Nitrotoluene or ortho-nitrotoluene is an organic compound with the formula CH 3 C 6 H 4 NO 2. It is pale yellow liquid that crystallizes in two forms, called α (−9.27 °C) and β (−3.17 °C). It is mainly a precursor to o-toluidine, which is an intermediate in the production of various dyes. [4]
