Lagerspets, Emi; Abba, Donatella; Sharratt, Joseph; Eronen, Aleksi; Repo, Timo published an article in 2022. The article was titled 《Water tolerant base free Copper (I) catalyst for the selective aerobic oxidation of primary alcohols》, and you may find the article in Molecular Catalysis.Quality Control of 2,6-Pyridinedimethanol The information in the text is summarized as follows:
Authors report here a base free copper(I) catalyst for the selective aerobic oxidation of primary alcs. to their corresponding aldehydes and various diols to their corresponding lactones or lactols. In the presence of the in situ generated Cu(I)-catalyst with 2,2′-dipyridylamine (dpa) as a ligand and 2,2,6,6-tetramethylpiperdine-N-oxyl (TEMPO) as a persistent radical, the oxidation reaction proceeds under true aerobic conditions, at ambient temperature, utilizing air as the oxidant and without added base. High catalytic activity without over oxidation was achieved for numerous primary alcs. (aliphatic, allylic, benzylic and diols) with different substitution patterns. The catalyst’s stability is unique among reported Cu(I)-catalysts. It is not moisture or air sensitive, and is capable of e.g. oxidizing aliphatic and benzyl alcs. in a water/acetonitrile solution in moderate or in quant. yield (> 99%) in 3 h. In the experiment, the researchers used 2,6-Pyridinedimethanol(cas: 1195-59-1Quality Control of 2,6-Pyridinedimethanol)
2,6-Pyridinedimethanol(cas: 1195-59-1) belongs to pyridine. Pyridine is widely used in the precursor to agrochemicals and pharmaceuticals. Also, it is used as an important reagent and organic solvent.Quality Control of 2,6-Pyridinedimethanol
