The estimation of the density and detonation properties of C, H, N, O, F explosives is discussed. A simple computer program, “Energy”, first developed at the Naval Weapons Center-China Lake in the early 1980’s is presented in an updated form. T

4,4′-(Methylenediimino)bis-1,2,5-oxadiazole-3-carboxylic acid and 4,4′-(methylenediimino)bis-1,2,5-oxadiazole-3-carboxamide have been synthesized by the acid-catalyzed condensation of 4-amino-1,2,5-oxadiazole-3-carboxylic acid and 4-amino-1,2,5-o

Spiro-cyclic compounds frequently have screw-type symmetry (C2) and are therefore optically active even though they do not contain an asymmetric carbon atom. (R/S)-1,6-Dinitro-3,8-dioxa-1,6-diazaspiro[4.4]nonane-2,7-dione is such a molecule. A blind

Reaction coordinate mapping was used to study the reaction of 3,4-diamino[1,2,5]oxadiazole (3,4-diaminofurazan) and 3,4-diamino[1,2,5]thiadiazole with glyoxal. The thiadiazole was known to give a good yield of [1,2,5]thiadiazolo[3,4-b]pyrazine, where

We are developing a resin system that cures via triazole ring formation (cycloaddition reaction of azides with terminal alkynes) instead of the traditional oxirane/amine reaction. The high exothermicity of the azido/alkyne reaction is expected to yie

The unusual 12-membered ring compound, octahydro-5H,12H-4,11-methano-1H,7H-bis[1,2,5]oxadiazolo[3,4-d:3′,4′-j][1,7,3,9]dioxadiazacyclododecine is obtained from the acid catalyzed reaction of 3-amino-4-hydroxymethylfurazan with formaldehyde instea

The crystal structures of the two compounds reported to be 4-aminofurazan-3-carboxylic acid have been determined. The compound reported by Sheremetev et al. (J Heterocycl Chem 2005, 42, 519) is the actual 4-aminofurazan-3-carboxylic acid. The compoun

The reaction of five- and six-membered cyclic thiourethanes with acetyl nitrate results in a vigorous reaction that generates copious amounts of red–brown nitrogen oxide fumes and produces the corresponding cyclic N-nitrourethanes in high yields (>

Reaction of amino(hydroxymethyl)furazan (II) with formaldehyde unexpectedly provides polycyclic compound (IV) instead of the expected bis(oxadiazolooxazine) (V).
