The reaction of activated aryl and heteroaryl halides with fluorinated alkoxide anions is described. In all cases, substitution of the halogen by a fluoroalkoxy group was observed. The effect of solvent, time, temperature, the activating group, leaving group, and the nucleophile on this reaction is also discussed.
