Nickel-Catalyzed Directed Cross-Electrophile Coupling of Phenolic Esters with Arylmethyl Trimethylammonium Triflates.

In this context, we successfully utilize polycyclic aryl-activated alkyl ammonium triflates as the electrophilic aryl-activated alkylating agent in the nickel-catalyzed hydroxyl- or sulfonamide-directed cross-electrophile coupling reaction with an array of phenyl benzoates, allowing for the synthesis of various aryl ketones under mild conditions.
