Reaction of o-halonitrobenzenes with sodium azide under reflux of DMF/H2O gives benzofuroxans in one step in moderate to good yields. This is a faster methodology compared to the conventional procedure involving the preparation and subsequent pyrolysis of o-nitrophenyl azides. For comparison, the reaction was also performed under phase-transfer catalysis. © 2017 Taylor %26 Francis.
