Reactions of F2NC(NO2)(3) with metal fluorides (KF and CsF) in DMF yield a substitution product of the fluorine atom for one nitro group, F2NC(NO2)(2)F. The reaction of F2NC(NO2)(3) with LiBr in ethanol or DMF affords Br(NO2)C=NF rather than the expected bromo derivative F2NC(NO2)(2)Br.

Methods for the preparation of α-azidopolynitroalkanes by reactions of polynitroalkanes or α-(difluoroamino)polynitroalkanes with NaN3 were developed. In the case of tetranitromethane, one or two nitro groups can be substituted, depending on the reaction conditions. The reaction of 1,1,1-trinitroethane with NaN3 affords nitro-1,2,3-triazole, together with 1-azido-1,1-dinitroethane. The IR spectra of
