The amination of benzofuroxan 2a and monosubstituted benzofuroxans 2b-e with alkali metal salts of formanilides 1 and sodium acetanilides 6 is described.Thus, the reaction of 2a with 6a-d gives the benzotriazole 1-oxides 3a-d.The benzofuroxans 2b and 2c react with sodium formanilides to give the isomeric mixtures 3f/3g and 3h/3i.Potassium 4-nitroformanilide reduces 2a furnishing benzofurazan 7.Nitrosubstituted benzofuroxans such as 2d and 2e undergo a carbocyclic amination leading to the benzofurazans 8 and 9.
