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. Depending on the conditions, oxidation yields 4-nitrobenzaldehyde diacetate, [6] 4-nitrobenzenoic acid, [7] and 4,4'-dinitrobibenzyl. [8]
2-Tolidine (orthotolidine, o-tolidine; not to be confused with o-toluidine) is an organic compound with the chemical formula (C 6 H 4 (CH 3)NH 2) 2. Several isomers are known; the 3-tolidine derivative is also important commercially. It is a colorless compound although commercial samples are often colored. It is slightly soluble in water.
This synthesis employs a condensation reaction of organolithium reagents derived from 2-alkyl-N-trimethylsilyl anilines by esters or carboxylic acids to yield substituted indoles. [6] This synthesis has proven applicable to a wide variety of substituted anilines, including those with alkyl , methoxy , and halide groups, and can react with non ...
Computer-assisted organic synthesis software is a type of application software used in organic chemistry in tandem with computational chemistry to help facilitate the tasks of designing, predicting, and producing chemical reactions. CAOS aims to identify a series of chemical reactions which, from a starting compound, can produce a desired molecule.
4-Chloro-o-toluidine (4-COT, 4-chloro-2-methylaniline) is the organic compound with the formula CH 3 C 6 H 3 Cl(NH 2). It is a colorless solid. The compound is produced as an intermediate to the pesticide chlordimeform and a precursor to some azo dyes. Production has declined after it was shown to be highly carcinogenic.
This reaction affords a 2:1 mixture of 2-nitro and 4-nitro isomers. [4] Chlorination of 2-nitrotoluene gives two isomers of the chloronitrotoluenes. Similarly nitration gives two isomers of dinitrotoluene. 2-Nitrotoluene is mainly consumed in the production of o-toluidine, a precursor to dyes. [4]
