Phenols are oxidatively fluorinated by reaction with sulfur tetrafluoride in hydrogen fluoride solution at about 0.degree. to 250.degree. 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 ##STR1## WHERE A AND B ARE FLUORINE, OR TOGETHER ARE CARBONYL OXYGEN, c and f, alike or different, are chlorine, bromine, CF.sub.3 or SO.sub.2 F, e is hydrogen, chlorine or SO.sub.2 F, 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 ##STR2## WHERE S, T AND U, ALIKE OR DIFFERENT, ARE CHLORINE, BROMINE OR FLUORINE.
苯酚在氢氟酸溶液中与四氟化硫反应,反应温度在0℃至250℃之间,被氧化氟化,形成可用作聚合物溶剂和/或增塑剂的产物。该过程的新产品包括结构式为##STR1##的1-氟-2-羟-2,5-环己二烯,其中A和B为氟,或者一起为羰基氧,c和f相同或不同,为氯、溴、CF.sub.3或SO.sub.2 F,e为氢、氯或SO.sub.2 F,d为氯或氟,或e和f一起为1,3-丁二烯-1,4-二基基;以及结构式为##STR2##的1,1,3,5-四氟-2,4,6-三卤-4-(3,5-二氟-2,4,6-三卤苯氧基)-2,5-环己二烯,其中S、T和U相同或不同,为氯、溴或氟。
