The CsF-assisted reactions of syn and anti-NCCFNF with Cl2 and Br2 and the uncatalyzed addition of ClF are described. Chlorine reacts only with the imine function, whereas Br2 reacts with both carbon-nitrogen multiple bonds. The more reactive syn isomer is isomerized to the anti- isomer under the reaction conditions. Six new compounds are reported and their structures assigned by 19F NMR and infrared
