3,4-Bis(bromomethyl)furazan and its N-oxide.

The conditions for bromination of the methyl groups of dimethylglyoxime were found, and the resulting product, a 1,4-dioxane solvate of bis(bromomethyl)glyoxime, was used as a precursor for heterocyclizations involving cyclodehydration or oxidative cyclization of the oxime groups leading to the formation of furazan and furoxan rings, respectively.
