Nickel-Catalyzed Deoxycyanation of Activated Phenols via Cyanurate Intermediates with Zn(CN)2: A Route to Aryl Nitriles

A novel, and efficient nickel-catalyzed deoxycyanation of phenolic compounds using relatively nontoxic Zn­(CN)2 as the cyanide source was developed. The reaction of C–O bond activated phenolic compounds by 2,4,6-trichloro-1,3,5-triazine with Zn­(CN)2 in the presence of a nickel precatalyst afforded the aromatic nitriles in good to excellent yields.
