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-electrophilecoupling reaction with an array of phenyl benzoates, allowing for the synthesis of various aryl ketones under mild conditions.

electrophilic acyl source in the reaction with diverse primary and secondary unactivated alkyl bromides. The cleavage of the relatively inert C–O bond is facilitated by the neighboring coordinating hydroxyl or sulfonamide moiety. By circumventing the use of pregenerated organometallics, this method allows efficient preparation of a variety of o-hydroxyl and tosyl-protected o-amino aryl ketones with high compatibility
