    • 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.
    • 氟化醚的制造方法包括在极性非质子传递溶剂:由式X-Rf 1 CH 2 OH表示的氟化醇和由式Rf2CH2OS(= O)2Rf3表示的氟化磺酸酯)和碱的组合; 得到式Y-Rf 1 CH 2 OCH 2 R f 2 -Y表示的氟代醚。 Rf1选自具有1至10个碳原子的全氟化C 1 -C 10亚烷基和部分氟化的C 1 -C 10亚烷基,及其具有连接的杂原子的衍生物。 X表示H,F或HOCH 2 - 基团。 Rf2选自全氟化的C 1 -C 10烷基和部分氟化的C 1 -C 10烷基,以及其具有连接的杂原子的衍生物。 Rf 3是C 1 -C 4烷基。 Y表示H,F或Rf2CH2OCH2-基团。 还公开了可用于制备对称氟化醚的变体方法。 本公开还提供了根据该方法可制备的氟化醚。 还公开了在各种应用中使用氟化醚。
