Abstract

Nitropyrazoles are structural units found in biologically active compounds (cholesterol lowering, antiinflammatory, anticancer, antidepressant and antipsychotic agents), dyestuffs, and recently high-energy materials. [ 1–7 View all references ] Several di- and trinitropyrazoles were synthesized using different nitration mixtures. [ 8–12 View all references ] The C-nitropyrazoles are obtained by rearrangement of N-nitropyrazoles in chlorobenzene, nitrobenzene, ...
