Regioselective nucleophilic substitution of perfluoropyridine with functionalized phenols provided a facile route toward the preparation of 2,6-bis(4-ethynylphenoxy)-3,5-difluoro-4-phenoxypyridine, a monomer that can be polymerized neat via thermal [2 + 2

Polyfluoro-substituted unsymmetrical biaryl ethers were synthesized via a novel Ni-catalyzed cross-coupling reaction of polyfluoroarenes with arylboronic acids and oxygen. The polyfluorinated arenes presumably captured the phenoxide intermediate efficiently, which made the oxygen-insertion proceed smoothly via the SNAr protocol. The 18O labeling experiment demonstrated that the oxygen introduced into unsymmetrical diaryl ether originated from very trace amounts of oxygen in the reaction system. A plausible mechanism was also suggested.

The kinetics of the reactions of pentafluoropyridine with potassium aroxides, leading to formation of polyfluorinated aryl pyridyl ethers, conform to the Bronsted equation. The data obtained for potassium pentafluorophenoxide deviate from the general corr
