The reaction of glyoxime (4) and hydroxylamine hydrochloride in aqueous sodium hydroxide was found to be a safe and inexpensive method for the preparation of multigram quantities of diaminoglyoxime (5). Potassium hydroxide mediated dehydration of 5 furnished diaminofurazan (1) in good yield of exceptional purity. The ready availability of 1 and 5 has facilitated the synthesis of new energetic furazan derivative 8.
Diazidoazofurazan 8 was obtained from the bis‐diazonium salt of diaminoazofurazan 7 by treatment with sodium azide and underwent thermolysis to 5‐[4‐azido‐(1,2,5)oxadiazolyl]‐5H‐[1,2,3]triazolo[4,5‐c][1,2,5] oxadiazole 5. The corresponding amine 13 was obtained from the azide 5 by reduction with stannous chloride and was oxidized by ammonium persulfate to 5‐[4‐nitro‐(1,2,5)oxadiazolyl]‐5H‐[1,2,3]triazolo[4,5‐c][1,2,5]oxadiazole 1. The azide 5 was converted to a phosphinimine 9 in a reaction with triphenylphosphine.
Diphenylcyclopropenone oxime combined with phenyl isocyanate to give 1,2,7-triphenyl-4-[(phenylamino)carbonyl]-5-oxa-4,7-diazaspiro-[2.4]hept-1-en-6-one.
Trinitrometlzane combined with oximes of cyclopentanone, cyclohexanone, and diphenylcyclopropenone and with melamine and two 1,3-dialky1-2,4-dialkylimino-l,3-diazetidines to give simple trinitromethanide salt adducts. Tricyanomethane added to diphenylcyclopropenone oxime to give hydroxylamino-2,3diphenylcyclopropenyliurn tricyanomethanide.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
