Aryl pentafluorobenzenesulfonates and nonaflates were identified to be good substrates for palladium-catalyzed cyanation reactions under very mild conditions using nontoxic, environmentally benign potassium hexacyanoferrate as a cyanide source. A wide range of electronically biased and sterically challenging substrates provided the corresponding the nitriles in very good yields.
