ABSTRACT:
The compound 7-amino-4,6-dinitrobenzofuroxan is synthesized by stirring monochloro-4,6-dinitrobenzofuroxan in CH.sub.2 Cl.sub.2 under an ammonia atmosphere. The position of the amino group is proved by reduction with triphenylphosphine to give 7-amino-4,6-dinitrobenzofurazan, a known compound.
