A Ni-catalyzed desymmetrizing cross-electrophile coupling of cyclic meso-anhydrides with aryltriflates has been successfully demonstrated. This is the only example using cyclic meso-anhydrides in cross-electrophile coupling reactions. A diverse array of valuable γ-keto acid building blocks can be generated under these conditions with excellent functional group tolerance and stereochemical fidelity

introduction of molecular complexity through the use of functionalized coupling partners. Regioselective alkylation of an unsymmetrical succinic anhydride and a profound effect of pendent coordinating olefins on reaction rate suggest a mechanism involving discrete oxidative addition of the nickel complex into the cyclicanhydride followed by a transmetalation event.
