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.

Aus den Zimtsäurechloriden (I) werden mit Selenophenol (II) die Selenophenylester (IIIa) und (IIIb) erhalten, von denen (IIIa) mit AlCl3 und Benzolabspaltung zu den Selenacumarinen (IVa) und (IVb) cyclisiert werden.

A Convenient Synthesis of Diaminoglyoxime and Diaminofurazan: Useful Precursors for the Synthesis of High Density Energetic Materials. -The reaction of glyoxime (I) with hydroxylamine in aqueous sodium hydroxide is a safe and inexpensive method for the preparation of multigram quantities of diaminoglyoxime (II), which provides the diaminofurazan (III) by KOH-mediated dehydration in good yield and exceptional purity. Furazan (III) is shown to be a useful precursor for the preparation of the new high density energetic compounds (VI) and (VII). -(GUNASEKARAN, A.; JAYACHAN-DRAN, T.; BOYER, J. H.; TRUDELL, M. L.; J.
