A new catalytic approach for aerobic oxidation of primary alcohols based on a Copper(I)-thiophene carbaldimines was written by Lagerspets, Emi;Valbonetti, Evelyn;Eronen, Aleksi;Repo, Timo. And the article was included in Molecular Catalysis in 2021.Related Products of 1777-82-8 This article mentions the following:
Novel Cu(I) thiophene carbaldimine catalysts for the selective aerobic oxidation of primary alcs. to their corresponding aldehydes and various diols to lactones or lactols was reported. In the presence of the in-situ generated Cu(I) species, a persistent radical (2,2,6,6-tetramethylpiperdine-N-oxyl (TEMPO)) and N-methylimidazole (NMI) as an auxiliary ligand, the reaction proceeds under aerobic conditions and at ambient temperature Especially the catalytic system of 1-(thiophen-2-yl)-N-(4-(trifluoromethoxy)phenyl)methanimine with copper(I)-iodide showed high reactivity for all kind of alcs. (benzylic, allylic and aliphatic). In the case of benzyl alc. even 2.5 mol% of copper loading gave quant. yield. Beside high activity under aerobic conditions, the catalysts ability to oxidize 1,5-pentadiol to the corresponding lactol (86% in 4 h) and N-phenyldiethanolamine to the corresponding morpholine derivate lactol (86% in 24 h) is particularly noteworthy. In the experiment, the researchers used many compounds, for example, (2,4-Dichlorophenyl)methanol (cas: 1777-82-8Related Products of 1777-82-8).
(2,4-Dichlorophenyl)methanol (cas: 1777-82-8) belongs to alcohols. Because alcohols are easily synthesized and easily transformed into other compounds, they serve as important intermediates in organic synthesis. Secondary alcohols are easily oxidized without breaking carbon-carbon bonds only as far as the ketone stage. No further oxidation is seen except under very stringent conditions.Related Products of 1777-82-8
