A novel and efficient method for the synthesis of polyfluoroarenesulfonyl bromides from polyfluoroarenethiols
The first general methodology has been developed for the synthesis of polyfluoroarenesulfonyl bromides from polyfluoroarenethiols. At heating of polyfluoroarenethiols with a mixture of Br2 and fuming HNO3 or Br2, HNO3 and H2SO4 polyfluoroarenesulfonyl bromides were obtained in good yields.
