In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called The oxidation of pyridine and alcohol using the Keggin-type lacunary polytungstophosphate as a temperature-controlled phase transfer catalyst, published in 2011-03-01, which mentions a compound: 2402-95-1, mainly applied to pyridine oxide preparation; oxidation pyridine polytungstophosphate catalyst; ketone preparation; alc oxidation polytungstophosphate catalyst, Product Details of 2402-95-1.
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.
There is still a lot of research devoted to this compound(SMILES：ClC1=CC=CC=[N+]1[O-])Product Details of 2402-95-1, and with the development of science, more effects of this compound(2402-95-1) can be discovered.
