Synthesis of di(polyfluoroalkyl) ethers

New procedures for preparing di(polyfluoroalkyl) ethers by reactions of polyfluoropropyl chlorosulfonites with polyfluorinated alcohols were tested.

METHODS OF MAKING FLUORINATED ETHERS, FLUORINATED ETHERS, AND USES THEREOF

A method of making a fluorinated ether includes combining, in a polar aprotic solvent: a fluorinated alcohol represented by the formula X—Rf1CH2OH, and a fluorinated sulfonate ester represented by the formula Rf2CH2OS(═O)2Rf3, and base; and obtaining a fluorinated ether represented by the formula Y—Rf1CH2OCH2Rf2—Y. Rf1 is selected from perfluorinated C1-C10 alkylene groups having from 1 to 10 carbon atoms and partially fluorinated C1-C10 alkylene groups, and derivatives thereof having catenated heteroatom(s). X represents H, F, or an HOCH2— group. Rf2 is selected from perfluorinated C1-C10 alkyl groups and partially fluorinated C1-C10 alkyl groups, and derivatives thereof having catenated heteroatom(s). Rf3 is a C1-C4 alkyl group. Y represents H, F, or an Rf2CH2OCH2— group. A variant method, useful for preparing symmetric fluorinated ethers, is also disclosed. The present disclosure also provides fluorinated ethers preparable according to the methods. Use of fluorinated ethers in various applications is also disclosed.

METHOD FOR PRODUCTION OF FLUOROALYKYLFLUOROALKANE-SULFONATE

PROBLEM TO BE SOLVED: To provide a method for simply producing, under more moderate condition than heretofore, a fluoroalkylfluoroalkane-sulfonate useful as an intermediate for medicines or agrochemicals and as a reagent for introducing a fluorine-containing group. SOLUTION: The fluoroalkyl fluoroalkane-sulfonate is produced by reacting a perfluoroalkanesulfonyl halide with a fluorine-containing alcohol in the presence of a base. In this case, an organic solvent is not used but water coexists as a solvent. It is particularly preferable that a reaction temperature is ≥-10°C but ≤40°C and water content is ≥0.2 g and ≤5 g per 1 g of the fluorine-containing alcohol. According to this method, for example, 2,2,2-trifluoroethyltrifluoromethane-sulfonate or 2,2,3,3-tetrafluoropropyltrifluoromethane-sulfonate can efficiently be produced, and the discharge amount of waste materials can remarkably be reduced.
