Difluoroamine does not react with tetranitromethane and fluoro-, chlor
o-, and bromotrinitromethanes in DMF and in acidic media (CF3COOH, ClS
O3H, FSO3H, and oleum), but reacts with alpha-fluoro- and alpha-(diflu
oroamino)-alpha,alpha-dinitrotoluenes to give substitution products of
the difluoroamino group for both the nitro groups, vit., PhC(NF2)(2)F
and PhC(NF2)(3), respectively.
