Do-it-yourself oxidation: The RhIII complex 1 undergoes a self-oxidative coupling process, in which the phenolate oxygen atom serves as the oxidant, to give 2 and the hydride complex 3 (2:3=1:3). This reaction involves cleavage of a strong aryl–oxygen bond. X-ray analysis of 2 reveals that the two quinonoid CO bonds are η2-coordinated to the metal centers.
