Novel highly energetic pyrazoles: N-fluorodinitromethyl and N-[(difluoroamino)dinitromethyl] derivatives

Treatment of 1,1-dinitro-1-(3,5-dinitropyrazol-1-yl)methanide with electrophilic fluorinating or difluoroaminating agents affords the corresponding fluorodinitromethyl or (difluoroamino)dinitromethyl pyrazole derivatives. Single crystal X-ray diffraction analysis shows a remarkable high density and DSC exhibits acceptable thermal stability of the compounds.
