Vinogradov, V. M. published the artcileNitropyrazoles. 4. N-Amination under pH control, SDS of cas: 84406-63-3, the publication is Izvestiya Akademii Nauk, Seriya Khimicheskaya (1993), 1434-1436, database is CAplus.
N-amination of pyrazoles bearing nitro groups and other electron-withdrawing substituents with hydroxylamine-O-sulfonic acid under pH control was carried out. A series of previously unknown pyrazoles was prepared Basicities (pKBH+) of 1-aminopyrazole and 1-amino-4-nitropyrazole were measured, and differences in the basicity of C- and N-amino groups for pyrazoles were determined
