Synthesis of 1,2-Bis(trifluoromethylthio)arenes via Aryne Intermediates was written by Mesgar, Milad;Daugulis, Olafs. And the article was included in Organic Letters in 2017.Quality Control of 4-Iodo-1,2-dimethoxybenzene This article mentions the following:
A general method for synthesis of 1,2-bis-trifluoromethylthioarenes has been developed. Arynes generated from silylaryl triflates or halides react with bis(trifluoromethyl)disulfide to afford 1,2-bis-trifluoromethylthioarenes. Aryl, alkyl, ester, halide, and methoxy functionalities are compatible with reaction conditions. Use of bis(perfluoroaryl)disulfides gave moderate yields of aryne disulfenylation or cyclization to fluorinated dibenzothiophenes. In the experiment, the researchers used many compounds, for example, 4-Iodo-1,2-dimethoxybenzene (cas: 5460-32-2Quality Control of 4-Iodo-1,2-dimethoxybenzene).
4-Iodo-1,2-dimethoxybenzene (cas: 5460-32-2) belongs to iodide derivatives. Organic iodides are widely used in organic synthesis. Halogenation of aromatic hydrocarbons is a very important reaction via an electrophilic aromatic substitution. 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.Quality Control of 4-Iodo-1,2-dimethoxybenzene
