Shevelev, S. A. published the artcileInteraction of NH-azoles with O-fluorosulfonyl-N,N-difluorohydroxylamine. Synthesis of N-fluorosulfonylazoles, Formula: C2H2N4O2, the publication is Izvestiya Akademi Nauk, Seriya Khimicheskaya (1992), 2419-30, database is CAplus.
FSO2ONF2 (I) reacts with anions of NH-azoles (imidazoles, pyrazoles, 1,2,3-triazoles) yielding the corresponding N-fluorosulfonylazoles from which sulfonylbisazoles are obtained. N-Fluorosulfonylation occurs at nitrogen atom which is farthest from the most electron-accepting substituent. Anions of nonaromatic NH-acids (imides, primary N-nitramines) can undergo N-fluorosulfonylation, however the yield is low (<5%) and the products are significantly less stable than N-fluorosulfonylazoles. N-Fluorosulfonylation occurs as nucleophilic substitution at the sulfur atom of I.
Izvestiya Akademi Nauk, Seriya Khimicheskaya published new progress about 84406-63-3. 84406-63-3 belongs to triazoles, auxiliary class Triazole,Nitro Compound, name is 4-Nitro-2H-1,2,3-triazole, and the molecular formula is C17H14F3N3O2S, Formula: C2H2N4O2.
