The reaction between perfluorobenzophenone and aromatic amines 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
全氟二苯甲酮和芳香胺之间的反应是在一个或多个氟原子被取代的情况下进行的。这种取代的区域化学受溶剂极性、温度和胺的亲核特性控制。在酸或碱催化下,通过电环化或芳香亲核取代,邻苯胺基壬二苯甲酮可选择性地转化为吖啶或吖啶。
