(4FBnOH), mediated by (bc)Pd(OAc)2 (bc = bathocuproine). Although alcoholoxidation is thermodynamically favored over H2Q oxidation by more than 400 mV, the oxidation of tBuH2Q proceeds several orders of magnitude faster than 4FBnOH oxidation. Kinetic and mechanistic studies reveal that these reactions feature different rate-limiting steps. Alcoholoxidation proceeds via rate-limiting β-hydride elimination
