Page and Ffeasman [210] obtained 3,6- (or 2,5-) dinitrotoluene by reacting Caro s acid with 5-nitro-o-toluidine. Brady and Williams [211] used the same method... 

The reaction of anilines with nitromalonaldehyde to form the 3-nitro-quinolines (96) is carried out in two steps. The cyclization is best catalyzed by the corresponding aniline hydrochloride in acetic acid (Scheme 19).89,90 The yields range from 40 to 77%, except in the case of o-toluidine, where the yield is very low. The tetracyclic compound 97 has been similarly prepared from 3-aminonaphthostyril.89... 

In this case, the diazotization can be carried out satisfactorily according to the procedure given on page 246 for 3-nitro-4-toluidine, using 100 cc. concentrated hydrochloric acid and 120 g. ice for 0.25 mole o-nitroaniline. 

Oxidants suitable for the partial oxidation of amines to nitroso compounds are peroxy acids Caro acid, which is prepared in situ from potassium persulfate and sulfuric acid [195, 199 potassium peroxysulfate (Oxone) [295] peroxyacetic acid [i53], and peroxybenzoic add [1186], 3-Nitro-o-toluidine [195] and 5-nitro-o-toluidine [199] in aqueous-alcoholic solutions, when treated with a mixture of potassium persulfate and concentrated sulfuric acid, give 3-nitro-2-nitrosotoluene and 5-nitro-2-nitrosotoluene in respective yields of 60 and 55-66%. Organic peroxy acids convert 2,6-dihaloanilines into 2,6-dihalonitrosobenzenes (equation 497) [753, 1186]. p-Phenylenediamine (1,4-diaminobenzene) is oxidized by Oxone (2KHS05 KHS04 K2S04) in an aqueous suspension at room temperature to p-dinitrosobenzene in a quantitative yield [205]. 

If they are ingested, dyes and particularly those that have an azo group can be metabolized by the intestinal microflora or by the liver enzymes. So, their effects can occur in organs responsible for metabolism or elimination, like the liver and urinary tract. Skin metabolism may also be responsible for the transformation of dyes, for example, those from colored textiles that can leach from the fabric and migrate to the skin. For example Disperse Orange 3 is degraded to p-phenylenediamine (PPD) and nitro-aniline in the skin (Figure 1). Direct Blue 14 (Cl 23850), after azo reduction, converts to the aromatic amine o-toluidine and other amines when incubated with cultures of Staphylococcus aureus.
