Bis(4‐chloro‐3,5‐dinitro‐1 H ‐pyrazol‐1‐yl)methane 2 was obtained for the first time via the coupling reaction of 4‐chloro‐3,5‐dinitro‐1 H ‐pyrazole 1 as a promising precursor for new explosives. The careful selection of the reaction conditions enabled the coupling of 1 having the poor reactivity to produce 2 in a good yield. The target compound, bis(4‐azido‐3,5‐dinitro‐1 H ‐pyrazol‐1‐yl)methane 3 , was produced by the double azidation reaction of 2 in one step. Some explosive properties of 2 and 3 were characterized and 3 is expected to be a novel green primary explosive having superior explosive properties and better thermal stability than those of a widely used primary explosive, 2‐diazo‐4,6‐dinitrophenol .
