A novel and efficient method for the synthesis of Me sulfone derivatives RSO2Me [R = Ph, 4-MeC6H4, 2-thienyl, etc.] via palladium-catalyzed methylsulfonylation of aryl and alkyl iodides with di-Me sulfite was described. In the experiment, the researchers used many compounds, for example, 4-Iodo-1,2-dimethoxybenzene (cas: 5460-32-2Safety of 4-Iodo-1,2-dimethoxybenzene).
4-Iodo-1,2-dimethoxybenzene (cas: 5460-32-2) belongs to iodide derivatives. In general, organic iodides are light-sensitive and turn yellow during storage, owing to the formation of iodine. A typical method for synthesis of aromatic iodides is diazotization of primary aromatic amines followed by treatment of potassium iodide. Aliphatic alcohols are converted to alkyl iodides by treating with hydrogen iodide.Safety of 4-Iodo-1,2-dimethoxybenzene
