Flower-like core-shell nanospheres (Au@CeO2) were prepared and used as photocatalyst to synthesize 2,4,6-trisubstituted pyrimidines through the three-component reaction of primary alcs., secondary alcs. and benzamidine hydrochlorides with low catalyst loading. A synergistic effect of ceria and gold on the photocatalytic transformation was found, which strongly enhanced the yield of pyrimidines from 58% on Au NPs (6 mg, 3 mol%) up to 97% on Au@CeO2 (6 mg, 0.4 mol%). The catalyst has also been successfully applied to photocatalytic multicomponent reaction for the synthesis of triazine. The Au@CeO2 catalyst shows high photocatalytic activity, good recyclability and wide applicability to diverse substrates. 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. 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. 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.Quality Control of (4-Methoxyphenyl)methanol
