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.

Reaction of 2-chloropyrazine and 2-chloropyrimidine with phenols and alcohols in the presence of K2CO3 in DMSO results in high yielding SNAr coupling. The reaction works particularly well with phenols and yields are comparable or superior to the metal-catalysed couplings described in the literature.
