Synthesis of (1,2,4-Triazinyl)furazans

Russian Journal of Organic Chemistry
The interaction of (3-methylfurazanyl)- and (3-aminofurazanyl)amidrazones with 1,2-dicarbonyl compounds (ninhydrin, glyoxal and benzyl) was studied. It was shown that upon using glyoxal, only acyclic products of dimeric structure were formed, while the introduction of other studied 1,2-dicarbonyl compounds into the reaction led to the target (1,2,4 ...

3-(1-Adamantyl)Furazans

Chemistry of Heterocyclic Compounds, 2013
The reactivity of 3-(1-adamantyl)-4-aminofurazan was studied. Upon treatment with oxidizing reagents the amino group is oxidized to azo, azoxy, and nitro groups. The nitration of 3-(1-adamantyl)-4-aminofurazan with nitric acid provided the corresponding nitroamine.

Furazan N-oxides. Part 2. Synthesis and structure of some strained furazan N-oxides

Journal of the Chemical Society, Perkin Transactions 1, 1983
The strained furazan N-oxides (5) and (6) have been synthesised from norbornene and dicyclopentadiene by treatment with N2O3, thermal isomerisation of the resulting nitronitroso-adducts to the nitro-oximes [e.g.(9)], and subsequent dehydration at ambient temperature using SO3–DMF or CISO3H–DMF.
