Synthesis of chloropolyfluoroarenes from polyfluoroarenethiols and PCl5

Аннотация

Replacement of the thiol group in polyfluoroarenethiols with chlorine was performed by treating with PCl₅ as chlorinating agent. By heating in ampules at 200–220°C polyfluoro- and polyfluorochloroarenethiols with PCl₅ mono- and dichloropolyfluoroarenes and also 1,2,4-trifluorotrichlorobenzene were synthesized. Dichloropolyfluoroarenes contain chlorine atoms in ortho- and para-positions.
