Do‐it‐yourself oxidation : The Rh III 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 η 2 ‐coordinated to the metal centers.
