Phenols are oxidatively fluorinated by reaction with sulfur tetrafluoride in hydrogen fluoride solution at about 0 DEG to 250 DEG C. to form products which are useful as solvents and/or plasticizers for polymers. The novel products of this process include 1-fluoro-2-hydro-2,5-cyclohexadienes of the structure <IMAGE> WHERE A AND B ARE FLUORINE, OR TOGETHER ARE CARBONYL OXYGEN, C AND F, ALIKE OR DIFFERENT, ARE CHLORINE, BROMINE, CF3 or SO2F, e is hydrogen, chlorine or SO2F, and D IS CHLORINE OR FLUORINE, OR E AND F TOGETHER ARE 1,3-BUTADIEN-1,4-DIYL; AND 1,1,3,5-TETRAFLUORO-2,4,6-TRIHALO-4-(3,5-DIFLUORO-2,4,6-TRIHALOPHENOXY )-2,5-CYCLOHEXADIENES OF THE STRUCTURE <IMAGE> WHERE S, T AND U, ALIKE OR DIFFERENT, ARE CHLORINE, BROMINE OR FLUORINE.
