    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: Tetrafluoro-ethylene can be added to monoamines having oxyethyl or oxypropyl groups in aprotic polar solvents in the presence of alkali metals. The new monoamines obtained having the radicals tetrafluoro-ethyloxy-ethyl or tetrafluoro-ethyl-oxy-propyl are electrolyzed in anhydrous hydrofluoric acid, thus forming new monoamines in which all or nearly all hydrogen atoms of the starting compounds are replaced by fluorine.
