And the article was included in Polyhedron in 2022.Quality Control of (4-Methoxyphenyl)methanol This article mentions the following:
Treatment of Cu(OAc)2·H2O with salicylaldimine Schiff-base (C9H6N)N = CH(3,5-tBu2C6H2OH) (L1H), (Et2N)(CH2)2N = CH(3,5-tBu2C6H2OH) (L2H), (2-C5H4N)CH2N = CH(3,5-tBu2C6H2OH) (L3H) in refluxing ethanol afforded three mononuclear copper complexes [(L1)Cu(OAc)] (1), (L2)Cu(OAc) (2) and (L3)Cu(OAc) (3), resp. The three new complexes were fully characterized using elemental anal., IR and HR-MS, and X-ray diffraction anal. They all exhibited efficient catalytic activity in the oxidation of primary and secondary alcs. into the corresponding carbonyl derivatives with hydrogen peroxide (H2O2) as the oxidation agent. The catalytic system is operationally simple, clean and generates water as the only byproduct. In the experiment, the researchers used many compounds, for example, (4-Methoxyphenyl)methanol (cas: 105-13-5Quality Control of (4-Methoxyphenyl)methanol).
(4-Methoxyphenyl)methanol (cas: 105-13-5) 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.Quality Control of (4-Methoxyphenyl)methanol
