HCID 14228262, compound → 2,1,3-Benzoxadiazole, 4,6-dichloro-, 1-oxide

Participants

Reaction Steps

A mixture of 0.63 g (2.7 mmol) of 2,4-dichloro-6-nitroazidobenzene and 25 ml glacial acetic acid is made and is refluxed for three to six hours. This is then poured over ice water, filtered and washed with water to yield 0.51 g (92.1% yield) of 4,6-dichlorobenzofuroxan, having a melting point of 105 to 105.5° C. Experimental runs result in yields ranging from 75 to 92%. The material can be recrystallized from ethanol/water if desired.
