Some symmetric and asymmetric 4,4'-bis(dialkylamino)benzils have been synthesized through the nudeophilic substitutions of 4, 4'-difLuorobenzil with amines. Their structures have been characterized by EA, IR, :H NMR and MS spectra. When primary amines were employed for the reaction, both the substitution and condensation occured in the substrate molecule. The mechanism of this reaction was discussed as well.
