The reaction of 4,6-dinitrobenzofuroxan 1 with alkali metal salts of formanilides 2 affords ?-nitrogen bonded Meisenheimer complexes 3 which upon heating in water form 4-arylamino-5,7-dinitrobenzofurazans 5 in good yields.A one-pot procedure starting from 1 and formanilides in the presence of sodium hydroxide is also described.
