Kryska, Anna et al. published their research in Journal of Chemical Research, Synopses in 1999 | CAS: 3268-21-1

1,4-Diiodo-2,3,5,6-tetramethylbenzene (cas: 3268-21-1) belongs to iodide derivatives. Generally organic iodides can be divided into two classes of alkyl iodides and aryl iodides. Typical reactions of alkyl iodides include nucleophilic substitution, elimination, reduction, and the formation of organometallics. In the chemical industry, alkyl iodides serve as excellent alkylating agents and, specifically, methyl iodide is used as a methylating agent in the synthesis of various pharmaceutical drugs.HPLC of Formula: 3268-21-1

Improved, acid-catalyzed iodinating procedures for activated aromatics with (diacetoxyiodo)benzene as the oxidant was written by Kryska, Anna;Skulski, Lech. And the article was included in Journal of Chemical Research, Synopses in 1999.HPLC of Formula: 3268-21-1 This article mentions the following:

Activated aromatics are effectively converted, at room temperature and within 15 min, into the corresponding mono-, di- or tri-iodinated products in anhydrous I2-PhI(OAc)2-AcOH-Ac2O systems, acidified with catalytic amounts of concentrate H2SO4. In the experiment, the researchers used many compounds, for example, 1,4-Diiodo-2,3,5,6-tetramethylbenzene (cas: 3268-21-1HPLC of Formula: 3268-21-1).
