4,6-Dichloro-5-nitrobenzofuroxan reacts with aromatic and heterocyclic amines via the chlorine atom at the position 4 of the aromatic ring to give monоsubstitution products. In a similar reaction with piperazine, both amino groups undergo arylation to give a compound containing two benzofuroxan fragments.
