Abstract

original image

The first examples of metal-mediated (using RuIII 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 Carom[BOND]H activation. Mechanistic studies reveal the involvement of multiple metal redox states and nucleophilic addition of water at activated aromatic rings.
