Treatment of Cu(OAc)2·4H2O with 8-hydroxylquinoline-imine ligands [2-(ArN = Hc)-8-OH]C9H5N (Ar = 2,6-iPr2C6H3, L1H; Ar = 4-ClC6H4, L2H; Ar = 4-BrC6H4, L3H and Ar = 4-OMeC6H4, L4H) in refluxing EtOH gave the dual-ligand coordinated copper complexes [L2Cu] (1a–1d) in good yields, resp. All the four Cu complexes were characterized by IR, EPR, elemental anal. and HR-MS. Furthermore, the mol. structures of 1a and 1d were further confirmed by x-ray crystallog. anal. These complexes displayed high catalytic activity and good selectivity for aerobic oxidation of primary and secondary alcs. in the presence of TEMPO (2,2,6,6-tetramethyl-1-piperidinyloxyl) as the co-catalyst. The yields of desired aldehydes are decent (up to 84%) and the corresponding yields of ketones are at 78-91%. In the experiment, the researchers used many compounds, for example, (4-Methoxyphenyl)methanol (cas: 105-13-5Electric Literature of C8H10O2).
(4-Methoxyphenyl)methanol (cas: 105-13-5) belongs to ethers. 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. Ethers feature bent C–O–C linkages. In dimethyl ether, the bond angle is 111° and C–O distances are 141 pm. The barrier to rotation about the C–O bonds is low. The bonding of oxygen in ethers, alcohols, and water is similar. In the language of valence bond theory, the hybridization at oxygen is sp3.Electric Literature of C8H10O2
