Rearrangement of N-nitro-1,2,4-triazoles into 3-nitro-1,2,4-triazoles
Journal of the Chemical Society, Chemical Communications, 1972Syntheses of the N-nitro-1,2,4-triazoles (1) and (2) and their thermal isomerization into the 3-nitroderivatives (3) and (4) is described; this thermal rearrangement of N-nitro-azoles to their corresponding C-nitro-compounds is suggested to be an example of a [1,5] sigmatropic shift of the NO2 group.

Hydroxyphenylazo-1,2,4-triazoles
Australian Journal of Chemistry, 1973Azo dyes have been prepared by coupling phenols with diazotized C- amino-1,2,4-triazole and p-aminophenyl-1,2,4-triazoles. Spectroscopic proofs of structure establish preferential para-coupling. The dyes exist in the azo form without evidence for quinone hydrazone tautomers. Spectroscopic evidence and chelation not involving the phenolic hydroxyl group
