A Direct Method for Oxidizing Quinoxaline, Tetraazaphenanthrene, and Hexaazatriphenylene Moieties Using Hypervalent λ3-Iodinane Compounds was written by Troian-Gautier, Ludovic;De Winter, Julien;Gerbaux, Pascal;Moucheron, Cecile. And the article was included in Journal of Organic Chemistry in 2013.Safety of 6-Bromoquinoxaline-2,3(1H,4H)-dione This article mentions 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. In the experiment, the researchers used many compounds, for example, 6-Bromoquinoxaline-2,3(1H,4H)-dione (cas: 1910-90-3Safety of 6-Bromoquinoxaline-2,3(1H,4H)-dione).
6-Bromoquinoxaline-2,3(1H,4H)-dione (cas: 1910-90-3) belongs to quinoxaline derivatives. Quinoxaline derivatives are important constituents of pharmacologically active compounds, including antibacterial, antibiotic and antineoplastic, antifungal, anti-inflammatory and analgesic drugs. The parent substance of the group, quinoxaline, results when glyoxal is condensed with 1,2-diaminobenzene. Substituted derivatives arise when α-ketonic acids, α-chlorketones, α-aldehyde alcohols and α-ketone alcohols are used in place of diketones.Safety of 6-Bromoquinoxaline-2,3(1H,4H)-dione
