Tandem Palladium-Catalyzed C-H Activation of Biaryls and Ring Opening of Benzofurans: Access to 2-(9-Phenanthryl)phenol Derivatives.

A palladium-catalyzed annulation of 2-iodo-1,1'-biaryl substrates, featuring concurrent ring opening of benzofurans, has been established to provide a direct and modular approach for the synthesis of a wide array of phenanthrene derivatives in modera…
