On June 30, 2021, Lagerspets, Emi; Valbonetti, Evelyn; Eronen, Aleksi; Repo, Timo published an article.Recommanded Product: 111-29-5 The title of the article was A new catalytic approach for aerobic oxidation of primary alcohols based on a Copper(I)-thiophene carbaldimines. And the article contained 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. The experimental process involved the reaction of Pentane-1,5-diol(cas: 111-29-5).Recommanded Product: 111-29-5
