The synthesis of sulfonyl compounds via sulfur dioxide insertion has received considerable attention from chemists recently. Various sulfonyl compounds such as sulfones, sulfonyl fluorides and sulfonamides have been prepared through the fixation of sulfur dioxide by employing sulfur dioxide surrogates. In particular, some of sulfur dioxide surrogates display a bifunctional role: not only serving as a source of sulfur dioxide, but also acting as a reducing agent in the desired sulfonylation reactions. The reductive sulfur dioxide anion radical plays a key role in these transformations, and the efficiency and atomic economy of these reactions have been enhanced greatly. This review highlights the recent advances of such bifunctional sulfur dioxide surrogates involved sulfonylation transformations.
