Synthesis of 3,4-Dihydro-1,2-diazete 1,2-Dioxides based on 1,2-Bishydroxylamines and 1,2-Nitroso Oxime

Oxidation of 1,2-bishydroxylamines having one or two hydroxylamino groups at a secondary carbon atom(s), by sodium hypobromite, leads to 3,4-dihydro-1,2-diazete 1,2-dioxides; treatment of 1,2-nitroso oxime with nitric acid or N₂O₄ gives 3,4-dihydro-3-nitro-1,2-diazete 1,2-dioxide.
