The first examples of metal‐mediated (using Ru III complexes) aromatic ring hydroxylation through ethereal oxygen insertion between two activated ortho ‐carbons of two different aryl rings are described by S. Goswami et al. in their Communication on page 2712 ff. Three similar reactions exemplify aromatic ring hydroxylation through double C arom H activation. Mechanistic studies reveal the involvement of multiple metal redox states and nucleophilic addition of water at activated aromatic rings.
