2,6-Difluoroaniline and several related primary amines are oxidised by peroxybenzoic acid in chloroform to the corresponding nitroso-compounds. Treatment of 2,6-difluoroaniline with sodium azide gives 4-fluoro-2,1,3-benzoxadiazole, which on nitration gives the 7-nitro-derivative.

calculated frequencies and forms of normal vibrations of compound (I) in the valence force field, the vibration spectrum has been interpreted. The presence and number of fluorine atoms in the phenyl fragments of azoxybenzenes have practically no effect on the stretching frequencies of the azoxy group but considerably decrease the band intensity of vibrations of the azoxy and phenyl groups in the Raman
