    • The beneficial effect of the ionic medium can be explained with the shielding of the positive charge of bulky tetraalkylammonium cations that would make the acetate counteranions more naked, thus enhancing their coordinating ability toward the palladium intermediate species of the catalytic cycle.

    • This reaction should proceed through the oxidation of the enolate anion by copper, the coupling of the radical with molecular oxygen, and the decomposition of the resulting peroxide by deprotonation with a base to give the ketone product.
