The synthesis of 6,9‐difluorobenzo[g]quinoline‐5,10‐dione ( 3b ) is described. Facile ipso substitutions of the fluorides from 3b by diamines readily yield the corresponding 6,9‐bis[(aminoalkyl)amino]benzo‐[g]quinoline‐5,10‐diones 2 . The analogue 2d has been synthesized by side arm modifications of dione 8a .
