Perfluoro(4-phenoxy-2,5-cyclohexadienone) reacts with sodium 4-nitro- and 4-methoxycarbonylphenoxides in glyme at 65°C to give the corresponding 2,4,6-trifluoro-3,5-bis(aryloxy)-4-[2,4,6-trifluoro-3,5-bis(aryloxy)phenoxy]-2,5 -cyclohexadienones. Reduction of the latter to phenols, followed by reaction with perfluorotoluene, results in formation of branched polyfluorinated polyphenyl ethers containing NO2 and COOCH3 functional groups. Reduction of the dinitro polyphenyl ether yields the corresponding diamino derivative. A similar reaction sequence gives rise to a linear polyphenyl ether, starting from 6-chloro-2,3,4,5,6-pentafluoro-2,4-cyclohexadien-1-one and tetrafluororesorcinol.
