Pd-catalyzed aerobic oxidative coupling of various benzoic acids with silyl enolesters proceeds via a combination of decarboxylation with sp3 β-C–H bond activation to give Heck-type products. Mechanistic studies reveal this coupling involves in situ generation of olefin from aerobic oxidation of silyl enolate, followed by decarboxylative Heck coupling.
