Diazopyrazole containing two nitro groups in the ring – 4-diazo-3,5-dinitropyrazole – has been synthesised for the first time by diazotisation of the corresponding aminodinitropyrazole. 4-Diazo-3,5-dinitropyrazole reacts with salts of methylene-active compounds, CH2(CN)NO2 and CH2(COCH3)2, to give azo coupling products, whereas its interaction with nucleophiles such as Br–, N3 or H2O(H+) involves replacement of one of the nitro groups yielding 4-diazo-3-R-5-nitropyrazoles.
