Abstract
Azoles without N-substituents are oxidized with per-acids or perborate to the corresponding isomers separated through N-hydroxy substituted azoles. 1,2,4-Triazole and tetrazole produce two their O-benzyl deriva tives. Imidazole and 1,2,3-and 1,2,4-triazole can be di-oxygenated in low yields. N-Hydroxypyrazole is deoxygenated by per-acid.
