Sohmiya, Hajime et al. published their research in Chemistry Letters in 1991 | CAS: 3268-21-1

1,4-Diiodo-2,3,5,6-tetramethylbenzene (cas: 3268-21-1) belongs to iodide derivatives. In general, organic iodides are light-sensitive and turn yellow during storage, owing to the formation of iodine. 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.COA of Formula: C10H12I2

Solid-state organic reactions proceeding by pulverization of inorganic solid-supports. Reactions of iodosobenzene with unsaturated hydrocarbons on acid-treated silica gel was written by Sohmiya, Hajime;Kimura, Takahide;Bauchat, Patrick;Fujita, Mitsue;Ando, Takashi. And the article was included in Chemistry Letters in 1991.COA of Formula: C10H12I2 This article mentions the following:

Pulverization of solid mixtures of hydrogen halide-treated silica gels, PhIO, and alkenes or an alkyne in the absence of a solvent causes smooth and rapid reaction to give halogenated or oxidized products in good yields. Thus, treating trans-PhCH:CHPh with HCl-treated silica gel and PhIO in the solid state gives meso– and dl-PhCCl:CClPh in 65% overall yield. In the experiment, the researchers used many compounds, for example, 1,4-Diiodo-2,3,5,6-tetramethylbenzene (cas: 3268-21-1COA of Formula: C10H12I2).
