The ionic liquid 1-butyl-3-methylimidazolium nitrate ([Bmim][NO3]) was introduced as both the solvent and catalyst for the activation of the mol. oxygen related to the aerobic iodination of arenes, which provides an effective and practical strategy for the synthesis of aryl iodides. The presented procedure allows a series of alkoxyl-substituted benzenes and naphthalenes to undergo the aerobic iodination in high yields and selectivities at an ambient temperature of 40°C. Almost all the atoms in the iodine source can be transferred to the final products. In the experiment, the researchers used many compounds, for example, 4-Iodo-1-methoxy-2-methylbenzene (cas: 75581-11-2Category: ethers-buliding-blocks).
4-Iodo-1-methoxy-2-methylbenzene (cas: 75581-11-2) belongs to ethers. The oxygen atom in ethers are more electronegative than carbon, thus the hydrogens which are alpha to the ethers are more acidic than the simple hydrocarbons. At room temperature, ethers are pleasant-smelling colourless liquids. Relative to alcohols, ethers are generally less dense, are less soluble in water, and have lower boiling points. They are relatively unreactive, and as a result they are useful as solvents for fats, oils, waxes, perfumes, resins, dyes, gums, and hydrocarbons. Vapours of certain ethers are used as insecticides, miticides, and fumigants for soil.Category: ethers-buliding-blocks
