The base-mediated reactions of 1-chloromethyl-2-nitroguanidine with a series of tetrazoles in different solvents were studied. 1-[(5-Methyl-1H-tetrazol-1-yl)methyl]-2-nitroguanidine, 1-[(5-amino-1H-tetrazol-1-yl)methyl]-2-nitroguanidine, and 2-nitro-1-[(1H-tetrazol-1-yl)-methyl]guanidine were synthesized for the first time.

A new synthetic procedure was developed to obtain 1-hydroxymethyl-2- nitroguanidine from 2-nitroguanidine and formaldehyde without catalyst. Reactions of 2-nitroguanidine and its 1-methyl- and 1-phenylsubstituted derivatives with formaldehyde and urotropin under acid catalysis resulted in 4-nitriminotetrahydro1,3,5-oxadiazine and 2-nitriminohexahydro-1,3,5-triazine and their methyl- and phenyl-substituted derivatives, whose nitration with concn. HNO3 in the presence of acetic anhydride and concn. H2SO4 depending on the temperature conditions led to the formation of 4-nitrimino-3,5-dinitrotetrahydro-1,3,5-oxadiazine, 3-methyl-4-nitrimino5-nitrotetrahydro-1,3,5-oxadiazine, 2-nitrimino-5-nitrohexahydro-1,3,5-triazine, and 1,3,5-trinitro-hexahydro-1,3,5-triazine-2-one.
