Water as a hydrogen source in palladium-catalyzed reduction and reductive amination of nitroarenes mediated by diboronic acid was written by Zhou, Yanmei;Zhou, Haifeng;Liu, Sensheng;Pi, Danwei;Shen, Guanshuo. And the article was included in Tetrahedron in 2017.Category: ethers-buliding-blocks This article mentions the following:
An unprecedented palladium-catalyzed chemoselective reduction and reductive amination of nitroarenes with water as a hydrogen source mediated by diboronic acid is discovered. A series of aryl amines containing various reducible functional groups were obtained in good to excellent yields. In the experiment, the researchers used many compounds, for example, 3-Methyl-4-nitroanisole (cas: 5367-32-8Category: ethers-buliding-blocks).
3-Methyl-4-nitroanisole (cas: 5367-32-8) belongs to ethers. Ether is less polar than esters, alcohols or amines because of the oxygen atom that is unable to participate in hydrogen bonding due to the presence of bulky alkyl groups on both sides of the oxygen atom. But ether is more polar than alkenes. 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
