General Description

1,2,3-trimethyl-4-nitrobenzene is a chemical compound with the molecular formula C9H11NO2. It is a nitro derivative of benzene, meaning it contains a nitro group (-NO2) attached to the benzene ring. Benzene, 1,2,3-trimethyl-4-nitro- is also known as 1,2,3-trimethyl-4-nitrobenzene and has a yellow crystal-like appearance. It is commonly used as a starting material for the synthesis of various organic compounds and can be found in some industrial processes as a chemical intermediate. 1,2,3-trimethyl-4-nitrobenzene is also used in the production of dyes, perfumes, and other aromatic chemicals. It is important to handle this compound with care as it is toxic and can cause harmful effects if not properly managed.

Photochemical nitration by tetranitromethane. Part XXVI. Adduct formation in the photochemical reaction of 1,2,3-trimethylbenzene: The formation of 'double' adducts including nitronic esters

The photolysis of the charge-transfer complex of 1,2,3-trimethylbenzene and tetranitromethane gives a complex mixture of products, most of which arise by initial attack of trinitromethanide ion on the unsubstituted ring positions at C4(C6) and C5 of the radical cation of 1,2,3-trimethylbenzene. The products 7-19 are adducts resulting directly or indirectly from the addition of the elements of tetranitromethane to 1,2,3-trimethylbenzene, and the trinitromethyl aromatic compounds 22-25 are formed by eliminations from intermediate adducts. Six adducts are simple 'single' adducts, nitro-trinitromethyl adducts 7, 8, 10-12, while nitro cycloadduct 9 is formed by cycloaddition of nitro-trinitromethyl adduct 8. The remaining addition products are 'double' adducts, formed by secondary addition reactions initiated by attack of nitrogen dioxide on the buta-1,3-diene system of 'single' adducts, and include trinitro-trinitromethyl compounds 13 and 15, the hydroxy-dinitro-trinitromethyl compound 14, and a group of four nitronic esters 16-19 formed by nitro-denitrocyclization of initially formed hydroxy-trinitromethyl and nitro-trinitromethyl 'single' adducts. Minor amounts of other products are formed including two nitrodienones 21 and 22, and the rearrangement product, 4,5,6-trimethyl-2-nitrophenol (28), and the 2,3,4-trimethyl- and 3,4,5-trimethylnitrobenzenes 26 and 27. The modes of formation of the above products are discussed, and X-ray crystal structure determinations are reported for compounds 9, 13, 14, 18, 19, 22 and 29. Acta Chemica Scandinavica 1996.
