Simple Access to the Non-Oxidizing Lewis Superacid PhF[rightward arrow]Al(ORF)₃ (RF=C(CF₃)₃)

Lewis superacidity? In analogy to Brønsted superacids, Lewis superacids can be defined as Lewis acids that are stronger than the strongest conventional and commercially employed Lewis acid SbF5. The fluorobenzene complex PhF→Al(ORF)3 (RF=C(CF3)3) qualifies as an easily accessible, non‐oxidizing and...

Zusammenfassung:Lewis superacidity? In analogy to Brønsted superacids, Lewis superacids can be defined as Lewis acids that are stronger than the strongest conventional and commercially employed Lewis acid SbF5. The fluorobenzene complex PhF→Al(ORF)3 (RF=C(CF3)3) qualifies as an easily accessible, non‐oxidizing and stable Lewis acid that conforms with our Lewis superacidity criterion.
