Oxidative Povarov Reaction via sp³ C–H Oxidation of <i>N</i>‑Benzylanilines Induced by Catalytic Radical Cation Salt: Synthesis of 2,4-Diarylquinoline Derivatives

Oxidative Povarov reaction of <i>N</i>-benzylanilines was realized under catalytic radical cation salt induced conditions. The mechanism studies revealed that a radical intermediate was involved in this catalytic oxidation. This method provides a new way to synthesize 2,4-diarylquinoline derivatives
