Quality Control of 2-Chloropyridine 1-oxide. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: 2-Chloropyridine 1-oxide, is researched, Molecular C5H4ClNO, CAS is 2402-95-1, about The oxidation of pyridine and alcohol using the Keggin-type lacunary polytungstophosphate as a temperature-controlled phase transfer catalyst. Author is Ding, Yong; Zhao, Wei.
A novel temperature-controlled phase transfer catalyst of [(C18H37)2(CH3)2N]7[PW11O39] has been developed for the oxidation of pyridines and alcs. with hydrogen peroxide. The reactions were conducted in 1,4-dioxane, and high yields of the corresponding heterocyclic N-oxides and ketones were obtained under relative mild conditions. The catalyst could be easily recovered and reused after reaction with cooling. There was no discernable loss in activity and selectivity after several reaction cycles.
