The reactionbetween perfluorobenzophenone and aromaticamines proceeds with the substitution of one or more fluorine atoms. The regiochemistry of this substitution is controlled by solvent polarity, temperature, and nucleophilic character of the amine. o-Anilinononafluorobenzophenone can be selectively transformed into acridines or acridones by using acid or base catalysis through electrocyclization
