The palladium-catalyzeddirect acetoxylation and arylation of 2-aryloxypyrimidine has been described. The aromatic C−H bonds may be functionalized in moderate to excellent yields providing a facile method for the synthesis of phenol derivatives, which show antimycobacterial and herbicidal activities.

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 aromaticnitriles in good to excellent yields.
