  Base initiated aromatization/C O bond formation: a new entry to O-pyrazole polyfluoroarylated ethers

  摘要：

  A base initiated intermolecular SNAr reaction of pyrazolones with polyfluoroarenes was developed. The process involved the isomerization aromatization of pyrazolone followed by the C-O bond formation via the selective C-F bond cleavage. With this strategy, a wide range of O-pyrazole polyfluoroarylated ethers bearing diverse functional groups were synthesized in mild to good yields. Additionally, our method was also applied to the isoxazol substrates. (C) 2014 Elsevier Ltd. All rights reserved.
