A method of synthesizing nitro derivatives of 1H,4H-pyrazolopyrazole is developed, and some of its transformations are studied. 3-Methyl-6-nitro-, 3-carboxy(methoxycarbonyl, carbamoyl)-6-nitro-, 3-amino-6-nitro-, 3-nitro-, 3,6-dinitro-, 1,4-diacetonyl-3,6-dinitro-, and 1H,4H-3-aminopyrazolopyrazoles were obtained from 1H,4H-3-methylpyrazolopyrazole.Unsubstituted 1H,4H-pyrazolopyrazole, the first member of this series, was obtained for the first time.The compounds prepared were characterized by 1H, 13C, 14N, and 15N NMR spectroscopy.NH-Acidity and basicity of the series of pyrazolopyrazoles ...

Environmental concerns demand the replacement of ammonium perchlorate (AP) by a green oxidizer in composite propellants. Herein, we report the synthesis and characterization of a novel green high-density energetic oxidizer octanitropyrazolopyrazole (ONPP). With its high specific impulse (256 s), high density (1.997 g cm-3) and good thermal stability (160 °C), ONPP can potentially replace AP. This journal is
