On November 1, 2013, Troian-Gautier, Ludovic; De Winter, Julien; Gerbaux, Pascal; Moucheron, Cecile published an article.Formula: C8H5ClN2 The title of the article was A Direct Method for Oxidizing Quinoxaline, Tetraazaphenanthrene, and Hexaazatriphenylene Moieties Using Hypervalent λ3-Iodinane Compounds. And the article contained the following:
An efficient oxidation reaction of various electron-poor quinoxaline-core-containing compounds, such as quinoxalines, 1,4,5,8-tetraazaphenanthrenes, and 1,4,5,8,9,12-hexaazatriphenylene, using [bis(trifluoroacetoxy)iodo]benzene is reported. These compounds are converted into the corresponding quinoxalinediones in good to high yields at room temperature using an acetonitrile/water solvent mixture This unprecedented reaction should enable the synthesis of a wide variety of compounds useful in several fields of chem. The experimental process involved the reaction of 5-Chloroquinoxaline(cas: 62163-09-1).Formula: C8H5ClN2
The Article related to quinoxaline tetraazaphenanthrene hexaazatriphenylene hypervalent iodinane oxidation, quinoxalinedione derivative preparation trifluoroacetoxyiodobenzene, Heterocyclic Compounds (More Than One Hetero Atom): Pyrazines and Quinoxalines (Including Piperazines) and other aspects.Formula: C8H5ClN2
