1,4-Diiodo-2,3,5,6-tetramethylbenzene (cas: 3268-21-1) belongs to iodide derivatives. Organic iodides can be alkyl, alkenyl, or alkynyl, and all of them are very reactive toward with many kinds of nucleophiles. Iodo alkanes participate in a variety of organic synthesis reactions, which include the Simmons–Smith reaction (cyclopropanation using iodomethane), Williamson ether synthesis, Wittig reaction, Grignard reaction, alkyl coupling reactions, and Wurtz reaction.Formula: C10H12I2

Oxidation of Iodo- and Bromo-Substituted Polymethylbenzenes in the System PbO2-CF3COOH-CH2Cl2 was written by Sandzhieva, M. A.;Aryamova, E. S.;Sukharzhevskii, S. M.;Grinenko, E. V.;Vasilyev, A. V.. And the article was included in Russian Journal of Organic Chemistry in 2018.Formula: C10H12I2 This article mentions the following:

The oxidation of mono- and diiodo- and -bromo-substituted polymethylbenzenes (mesitylene and durene) in the system PbO2-CF3COOH-CH2Cl2 at room temperature (2-70 h) leads mainly to the formation of iodo- and bromobenzyl alcs. as result of oxidation of Me group. The reaction involves intermediate formation of haloarene radical cations. ESR study of these radical cations made it possible to determine the structure of their singly occupied MOs a2 or b1 and interpret their reactivity. In the experiment, the researchers used many compounds, for example, 1,4-Diiodo-2,3,5,6-tetramethylbenzene (cas: 3268-21-1Formula: C10H12I2).
