Studies on sulfinatodehalogenation XXIV. Further study on sodium dithionite-initiated perfluoroalkylation of electron-rich aromatics

The application of the sulfinatodehalogenation reaction system for the perfluoroalkylation of electron-rich aromatics is further studied. It was shown that perfluoroalkyl iodides reacted with polyhydric phenols, N,N?dialkylanilines, 2,5-dimethylpyrrole, N?methylpyrrole initiated by Na₂S₂O₄?NaHCO₃ gave the corresponding perfluoroalkylated products in moderate to good yields.
