Catalytic hydrodefluorination of pentafluorobenzene by [Ru(NHC)(PPh3)2(CO)H2]: a nucleophilic attack by a metal-bound hydride ligand explains an unusual ortho-regioselectivity.

The selective synthesis of fluoroarene compounds is a subject of intense current interest, driven by the prominent role such species play in many pharmaceuticals, agrochemicals, and other industrially important products. One attractive route to selectively substituted fluoroarenes involves the activation and functionalization of aromatic C F bonds derived… (More)
