Reaction of DMSO with phthalazinediones was written by Czuba, Wladyslaw;Sedzik-Hibner, Dorota. And the article was included in Universitatis Iagellonicae Acta Chimica in 1991.Name: 2-Methyl-2,3-dihydrophthalazine-1,4-dione This article mentions the following:
Treatment of 1,4-phthalazinedione with DMSO afforded 2-(methylthiomethyl)phthalazine-1,4-dione, 2,3-bis(methylthiomethyl)phthalazine-1,4-dione, and 4-(methylthiomethoxy)-2-(methylthiomethyl)phthalazin-1-one in a 8:3:3 ratio. In the experiment, the researchers used many compounds, for example, 2-Methyl-2,3-dihydrophthalazine-1,4-dione (cas: 18393-54-9Name: 2-Methyl-2,3-dihydrophthalazine-1,4-dione).
2-Methyl-2,3-dihydrophthalazine-1,4-dione (cas: 18393-54-9) belongs to phthalazine derivatives. Phthalazine is isomeric with other naphthyridines including quinoxaline, cinnoline and quinazoline. As with cinnolines, phthalazines were also prepared most frequently through condensations of hydrazine derivatives and carbonyl-containing compounds.Name: 2-Methyl-2,3-dihydrophthalazine-1,4-dione
