Safety of 8-Hydroxyquinoline 1-oxide. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 8-Hydroxyquinoline 1-oxide, is researched, Molecular C9H7NO2, CAS is 1127-45-3, 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.
