scheme or table, p. 95 - 97 (2012/07/03)
Treatment of o-halonitrobenzenes with sodium azide in a [empyrr][BF4]/Bu4NBr/H2O system gives benzofuroxans in high yields, with the recovery and reuse of the ionic liquid for at least ten times.
Substituent Effects in the Conversion of Azido- and Diazidotrinitrobenzenes to Benzofuroxans and Difuroxans

The preparation of a number of substituted dinitrobenzofurazan oxides (dinitrobenzofuroxans) and nitrobenzobis(oxadiozoles) (nitrobenzodifuroxans), in which the substituents were amino, fluoro, formamido, hydroxy, and ureido groups, by thermolysis of azid
A Novel Method for the Amination of 4,6-Dinitrobenzofuroxan via Meisenheimer Complexes

The reaction of 4,6-dinitrobenzofuroxan 1 with alkali metal salts of succinimide, phthalimide, and formamides affords ?-N-C bonded Meisenheimer complexes 3.The adducts 3a-c may be directly oxidized to the in 7-position aminated dinitrobenzofuroxan derivatives 6a-c by treatment with aqueous nitric acid.In the case of 6a the oxidation of 3a proceeds with loss of carbon monoxide.For the preparation of 6d-g the alkali metal salts 3d-g must be transformed to the corresponding silver salts 4d-g before oxidation.
