3,5-Dinitro-4-(phenylsulfonyl)pyrazole (5) obtained by oxidation of 3,5-dinitro-4-(phenylthio)pyrazole with 30% H2O2 in AcOH was involved into nucleophilic substitution reaction with thiophenol, which proceeded with substitution of t
Efficient procedure for high-yield synthesis of 4-substituted 3,5-dinitropyrazoles using 4-chloro-3,5-dinitropyrazole

The transformations of readily available 4-chloro-3,5-dinitropyrazole and its N-methylated derivative under the action of anionic S-/O-nucleophiles and neutral N-nucleophiles were studied. Independent of the substrate's charge (anionic, R=H, or neutral, R

experimental part, p. 253 - 254 (2011/05/04)
Nitration of 3,5-dinitropyrazole with HNO3-H2SO4 mixture gives 3,4,5-trinitro-1H-pyrazole, which in reaction with ammonia, amines or thiols under mild conditions undergoes regioselective nucleophilic substitution of the 4-positioned nitro group.
