Formation of 3,3,5,7-tetranitrooxindole and 3,5,7-trinitroindazole by nitration of oxindole. Bergman, Jan; Bergman, Solveig (Dep. Organic Chemistry, Royal Institute Technol., Stockholm S-100 44, Swed.There are some reagents like 20870-79-5 is used in this study.). Tetrahedron Letters, 37(51), 9263-9266 (English) 1996 Elsevier. CODEN: TELEAY. ISSN: 0040-4039. DOCUMENT TYPE: Journal CA Section: 27 (Heterocyclic Compounds (One Hetero Atom)) Nitration (HNO3/H2SO4) of oxindole [1,3-dihydro-2H-indol-2-one] gave 3,3,5,7-tetranitrooxindole, which readily underwent ring-opening and decarboxylation to 4,6-dinitro-2-(dinitromethyl)aniline, which in turn could be cyclized to 3,5,7-trinitroindazole. .
