Web6 Dec 2006 · Abstract. Although there have been a relatively large number of publications recently dealing with the reduction of sulfoxides fo sulfides 1,2 there are still very few general procedures for the reduction of sulfones to sulfides and none at all, as far as we are aware, for the reduction of sulfones to sulfoxides. In his paper dealing with the use of … WebIn addition, sulfones and sulfoxides are polar moieties that can lower the overall lipophilicity and improve the aqueous solubility and metabolic stability of a molecule, which can lead …

Even at 95 °C and with a two-fold excess of H 2 O 2 , oxidation to sulfone 9 proceeds only to 56% ( Table 1 , entry 3), and a full oxidation could only be achieved by refluxing the reaction mixture in acetic acid for 24 h ( Table 1 , entry 4).
Sulfones are typically prepared by organic oxidation of thioethers, often referred to as sulfides. Sulfoxides are intermediates in this route. For example, dimethyl sulfide oxidizes to dimethyl sulfoxide and then to dimethyl sulfone. Sulfur dioxide is a convenient and widely used source of the sulfonyl functional group. Specifically, Sulfur dioxide participates in cycloaddition reactions with d…
