At. Baryshnikov et al., GEM-DINITRO COMPOUNDS IN ORGANIC-SYNTHESIS .4. USE OF THE CONDENSATION PRODUCT OF GLYOXAL AND DINITROMETHANE IN THE SYNTHESIS OF NITRO-1,2,3-TRIAZOLES, Bulletin of the Russian Academy of Sciences, Division of Chemical Sciences, 41(9), 1992, pp. 1657-1664
The condensation of dinitromethane with glyoxal has been investigated
and it has been demonstrated that 1,1,4,4-tetranitro-2,3-butandiol, al
pha-hydroxy-beta,beta-dinitropropionic acid or their mixture may be fo
rmed. Interaction of 1,1,4,4-tetranitro-2,3-butandiol or 1,4-dibromo-1
,1,4,4-tetranitro-2,3-butanediol diacetates with sodium azide leads to
bis(5-nitro-1,2,3-triazol-4-yl) via intermediate 1, 1,4,4-tetranitro-
1,3-butadiene.
