Synthesis of Perfluoro Crown Ethers: A New Class of Cyclic Fluorocarbons

摘要

The first perfluoro crown ethers, perfluoro-18-crown-6, perfluoro 15-crown-5 and perfluoro 12-crown-4, have been prepared by carefully controlled elemental fluorination. Although they are weaker bases, crown ethers are materials which will have a number of applications. Keywords: Fluorine compounds; Fluorocarbons; Reprints; Synthesis chemistry; Ethers; Fluorination; chemical stability. (KT)
