A NEW FACILE SYNTHESIS OF 4-ARYLAMINO-5,7-DINITROBENZOFURAZANS

Niclas, H.-J.,Goehrmann, B.,Gruendemann, E.

, p. 2789 - 2798 (2007/10/02)

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.
