WebChiral sulfoxides are important compounds that are finding increasing use as chiral auxiliaries in asymmetric synthesis and can be of interest to the pharmaceutical industry. … 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…

It is a polar functional group. Sulfoxides are oxidized derivatives of sulfides. Examples of important sulfoxides are alliin, a precursor to the … See more Sulfoxides feature relatively short S–O distances. In DMSO, the S–O distance is 1.531 Å. The sulfur center is pyramidal; the sum of the angles at sulfur is about 306°. Sulfoxides are generally represented with the structural … See more DMSO is a widely used solvent. The sulfoxide functional group occurs in several drugs. Notable is esomeprazole, the optically pure … See more Sulfoxides are typically prepared by oxidation of sulfides, sometimes referred to as sulfoxidation. hydrogen peroxide is a typical oxidant, but periodate has also been used. In these oxidations, care is required to avoid over oxidation to form the See more Deoxygenation and oxygenation Sulfoxides undergo deoxygenation to give sulfides.

WebFor the oxidation of sulfides into their corresponding sulfoxides and sulfones, a number of procedures have been described, including stoichiometric reactions, chemocatalytic reactions, and bio-catalytic reactions . The main goal of this kind of transformation is the selective preparation of the mono-oxygenated over the bis-oxygenated derivatives, and … WebThe sulfinyl sulfones generated in situ from sulfinates in the presence of an acylating reagent were able to trap the alkyl radicals that were produced via the photoinduced direct hydrogen atom transfer of alkanes, leading to a range of sulfoxides. This radical sulfinylation process provides an efficient and concise method for the synthesis of ...
