Direct cyanations of arenes and heteroarenes bearing only weakly coordinating amides were accomplished using a robust ruthenium(II) catalyst. The user-friendly C(sp2)âH activation occurred with the assistance of carboxylate with high site-selectivity, excellent functional group tolerance and ample scope.
