2-nitroguanidine derivatives: X. Synthesis and nitration of 4-nitriminotetrahydro-1,3,5-oxadiazine and 2-nitriminohexahydro-1,3,5-triazine and their substituted derivatives
摘要:
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.

Manometry together IR spectroscopy, mass spectrometry, and chromatography were used to study thermolysis of six-membered cyclic N-nitramines containing one, two, or three nitramine fragments, as well as oxo, gem-dinitro, azide, nitroimino, amino, and tetrazolyl functions. An effect of the conformation and functional groups on the rate, mechanism, and activation parameters of the limiting stage of themolysis was revealed.
