摘要：
Palladium-catalyzed cyanation of aryl bromides with potassium hexacyanoferrate(II) trihydrate, K-4[Fe(CN)6]center dot 3H(2)O as the cyanide source gave benzonitrile derivatives using a catalytic amount of Pd(OCOCF3)(2) in DMF at 110 degrees C with phosphine-free pyridyl-hydrazone ligand 2c in good yields.
