Research Progress on the Oxidation of Thioether to Sulfoxide and Sulfone
Sulfoxide and sulfone are two important chemical compounds that have a wide range of ap-plications in chemistry and biology.Although there are many methods for the synthesis of sulfoxide and sul-fone,the chemically selective oxidation of thioether by controlling the chemical selectivity oxidation of thioether is one of the common ways to synthesize sulfoxide and sulfone,and common oxidants such as air/oxygen,hydrogen peroxide,potassium monopersulfate complex salt(Oxone),sodium periodate,etc.can achieve selective oxidation of thioether.In this paper,the oxidation reactions are classified according to the types of oxidants,and the research progress on the preparation of sulfoxide and sulfone by the oxidation of sulfide ether in recent years is reviewed.
