Metal-Free, Oxidant-Free, and Controllable Graphene Oxide Catalyzed Direct Iodination of Arenes and Ketones was written by Zhang, Jingyu;Li, Shiguang;Deng, Guo-Jun;Gong, Hang. And the article was included in ChemCatChem in 2018.Electric Literature of C8H5IS This article mentions the following:
A direct, metal-free, and oxidant-free method for the graphene oxide (GO)-catalyzed iodination of arenes and ketones with iodine in a neutral medium was explored. This iodination protocol was performed by using a simple technique to avoid the use of external metal catalysts and oxidants and harsh acidic/basic reaction conditions. In addition, by this method the degree of iodination could be controlled, and the reaction was scalable and compatible with air. This strategy opens a new field for GO-catalyzed chem. and provides an avenue for the convenient direct iodination of arenes and ketones. In the experiment, the researchers used many compounds, for example, 3-Iodobenzo[b]thiophene (cas: 36748-88-6Electric Literature of C8H5IS).
3-Iodobenzo[b]thiophene (cas: 36748-88-6) belongs to iodide derivatives. Organoiodine compounds occur widely in organic chemistry, but are relatively rare in nature. The C–I bond is the weakest of the carbon–halogen bonds. These bond strengths correlate with the electronegativity of the halogen, decreasing in the order F > Cl > Br > I.Electric Literature of C8H5IS
