Abstract: Phenols react with tetrafluoroethylene at normal or reduced pressure when using about 0.05 to about 0.5 mole of an alkali metal hydroxide per each equivalent of phenolic hydroxy group as a catalyst and a water-miscible polar inert solvent to yield aryl-1,1,2,2-tetrafluoroethyl ethers. The products are useful as intermediates in the synthesis of dyestuffs and plant-protecting agents.
Abstract translation: 当每当量酚羟基作为催化剂和与水混合的极性惰性溶剂使用约0.05至约0.5摩尔碱金属氢氧化物时，苯酚在正常或减压下与四氟乙烯反应，得到芳基-1,1,2， 2-四氟乙醚。 该产品可用作合成染料和植物保护剂的中间体。
