A Convenient Method for the Preparation of Symmetrical or Unsymmetrical Ethers by The Coupling of Two Alcohols via A New Type of Oxidation–reduction Condensation Using Tetrafluoro-1,4-benzoquinone

Abstract A new type of oxidation–reduction condensation by using tetrafluoro-1,4-benzoquinone (fluoranil), alcohols and alkoxydiphenylphosphines, in situ formed from nBuLi-treated alcohols and chlorodiphenylphosphine, proceeded smoothly to afford the corresponding symmetrical or unsymmetrical ethers in good to high yields.
