  Pd-catalyzed aerobic direct olefination of polyfluoroarenes

  摘要：

  The first example of Pd-catalyzed aerobic direct olefination of polyfluoroarenes has been developed. The reaction makes use of molecular O-2 as terminal oxidant, and provides a cost-efficient and environmentally benign access to polyfluoroarene-alkene structures that are of interest in life and material sciences.

  日期：2013.10.18

  A methyl(phenyl)sulfane-promoted direct olefination of polyfluoroarenes catalyzed by palladium has been reported. With use of this new thioether ligand, a high reaction efficiency and excellent E/Z ratio of desired olefinated polyfluoroarenes were obtained. This represents a first example of thioether promoted oxidative Heck reaction.
