In organic chemistry, a sulfoxide, also called a sulphoxide, is an organosulfur compound containing a sulfinyl (>SO) functional group attached to two carbon atoms. 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. Typically metal complexes are used to catalyze the … See more • Gama Á, Flores-López LZ, Aguirre G, Parra-Hake M, Hellberg LH, Somanathan R (2003). "Oxidation of sulfides to chiral sulfoxides using Schiff base-vanadium (IV) complexes". … See more WebThe bioconcentration of disulfoton and its oxidation products (sulfoxide and sulfone) in carp (Cyprinus carpio) was investigated in a continuous flow water system for ≤56 days (Takase and Oyama 1985). The whole-body BCF values in carp were ≈450 for disulfoton, <1 for the sulfoxide, and <6 for the sulfone. 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 … scum like you belong on a cross
