In this study, a search for syntheticroutes to never-before-seen tetrabenzylglycoluril was made and two synthetic strategies were examined: condensation of 1,3-dibenzylurea with glyoxal, and N-alkylation of glycoluril and its disubstituted derivative. The first synthetic approach furnished only a condensation product, 3,3′-bi(6,8-dibenzyl-2,4-dioxa-9,8-diazabicyclo[3.3.0]octan-7-one, bearing the dioxolane

approach to the synthesis of N-nitrosemicarbazones, promising high-energy and biologically active compounds. Subsequent treatment with amines and alkalis led to the synthesis of water-soluble salts of nitrosemicarbazones, as well as the corresponding semicarbazones. The reaction of N,N′-diisopropyl- or N,N′-di-tert-butyl-1,2-ethanediimine with 4-nitrosemicarbazide led to the synthesis of glyoxal bis

The structure of dinitrourea (DNU) as determined by X-ray single-crystal diffraction is orthorhombic; space group: Fdd2; a = 12.0015(9), b = 17.6425(13), c = 4.5555(4); V = 964.57 à 3, Z = 8, T = 90 K; Dc = 2.067 g cmâ3. The heat of formation (ÎfH°298) of DNU in the gas phase was calculated to be 24.88 kJ molâ1 by using the G3MP2 method based on isodesmic reactions. Eleven mono-organic salts of DNU were prepared in acetonitrile and characterized via NMR spectra, elemental analyses and DSC. Derivatives of 1,2,4-triazolium salts of DNU exhibit densities ranging from 1.75 to 1.86 g cmâ3 and detonation properties comparable with those of RDX and HMX.
