A visible light- and heat-promoted C-O coupling reaction of phenols and aryl halides was described to afford diaryl ethers in good to excellent yields without transition-metal, photocatalysts or ligands. Moreover, the reaction had good substrate universality, suitable for substituted phenol, naphthol and heterocyclic phenol derivatives Control experiments revealed that an electron donor-acceptor (EDA) complex formed from the association of an aryl halide and phenol anion. DFT calculation further confirmed the existence of the EDA complex. In the experiment, the researchers used many compounds, for example, 1-(4-(4-Methoxyphenoxy)phenyl)ethanone (cas: 54916-28-8SDS of cas: 54916-28-8).
1-(4-(4-Methoxyphenoxy)phenyl)ethanone (cas: 54916-28-8) 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. Ethers can form hydrogen bonds with other molecules (alcohols, amines, etc.) that have O―H or N―H bonds. The ability to form hydrogen bonds with other compounds makes ethers particularly good solvents for a wide variety of organic compounds and a surprisingly large number of inorganic compounds.SDS of cas: 54916-28-8
