2.4.6- Trimethyl-3-nitroaniline

To fight fire, use alcohol foam, CO2, dr) chemical. Violent polymerization occurs on contact with ammonia, alkali hydroxides, amines, metallic potassium, acids, covalent halides (e.g., aluminum chloride, iron(III) chloride, tin(IV) chloride, aluminum oxide, iron oxide, rust). Explosive reaction with glycerol at 200°. Rapid compression of the vapor with air causes explosions. Incompatible with bases, alcohols, air, m-nitroaniline, trimethyl amine, copper, iron chlorides, iron oxides, magnesium perchlorate, mercaptans, potassium, tin chlorides, contaminants, alkane thiols, bromoethane. When heated to... 

PAI with a deflnite head-to-tail backbone can be prepared by condensation of trimelliric acid anhydride with 4-amino-4-nitrodiphenyl ether. Then the nitro group is reduced to give a monomer having amine and acid functional groups. This monomer is subjected to direct polymerization. The procedure is useful for the preparation of dissymmetric polymers. Further compounds with amino groups and nitro groups are 3-nitroaniline, 2-methyl-5-nitroaniline, and, 3-nitromesidine, i.e, 2,4,6-trimethyl-3-nitro-aniline. 

The anodic chlorination in some cases allows one to achieve better regioselec-tivities than chemical alternatives (p/o ratio of chlorotoluene in chlorination of toluene anodic 2.2, chemical alternative 0.5-1.0) [215]. Anodic oxidation of iodine in trimethyl orthoformate afforded a positive iodine species, which led to a more selective aromatic iodination than known methods [216]. Aryliodination is achieved in good yield, when an aryhodide is oxidized in HOAc, 25% AC2O, 5% H2SO4 in the presence of an arene [217, 218]. Alkyl nitroaromatic compounds, nitroaromatic ketones, and nitroanilines are prepared in good yields and regioselectivity by addition of the corresponding nucleophile to a nitroarene and subsequent anodic oxidation of the a-complex (Table 13, number 11) [219, 220].
