An acid–base reaction to speed up a sluggish catalytic cycle! AcOH as the solvent enables extraordinarily fast and efficient PdII‐catalysed, directintramolecularallylicaminations, assisting the benzoquinone‐mediated palladium reoxidation and ionisation of the intermediate palladium complexes (see scheme). The structural and energetic aspects of such a key step of the catalytic cycle are illustrated
