Encyclopedia > Sulfone

A sulfone is a chemical compound containing a sulfonyl functional group attached to two carbon atoms. The central sulfur atom is twice double bonded to oxygen and has two further hydrocarbon substituents. The general structural formula is R-S(=O)(=O)-R' where R and R' are the organic groups. The use of the alternative name sulphone is discouraged by IUPAC. Sulfides are often the starting materials for sulfones by organic oxidation through the intermediate formation of sulfoxides. For example dimethylsulfide is oxidized to dimethyl sulfoxide and then to dimethyl sulfone. ... Sulfonyl is an organic radical (or functional group) obtained from an sulfonic acid by the removal of the hydroxyl group. ... In ecology functional groups are collections of organisms based on morphological, physiological, behavioral, biochemical, or environmental responses or on trophic criteria. ... General Name, Symbol, Number sulfur, S, 16 Chemical series nonmetals Group, Period, Block 16, 3, p Appearance lemon yellow Atomic mass 32. ... Covalent bonding is a form of chemical bonding characterized by the sharing of one or more pairs of electrons between atoms, in order to produce a mutual attraction, which holds the resultant molecule together. ... General Name, Symbol, Number oxygen, O, 8 Chemical series nonmetals Group, Period, Block 16, 2, p Appearance colorless Atomic mass 15. ... Many chemical compounds, especially hydrocarbons, can exist in different geometric configurations. ... The International Union of Pure and Applied Chemistry (IUPAC) is an international non-governmental organization devoted to the advancement of chemistry. ... In chemistry, a sulfide (sulphide in British and Canadian English) is a chemical compound or combination of sulfur with an oxidation number of -2, with another chemical element or a radical thereof. ... Organic reductions or organic oxidations or organic redox reactions are redox reactions that take place with organic compounds. ... A sulfoxide is a chemical compound containing a sulfinyl functional group with a sulfur oxygen double bond attached to two carbon atoms. ... Dimethylsulfide (DMS; CH3SCH3) is a volatile sulfur gas, and the most abundant single biological sulfur compound emmitted to the atmosphere. ... Dimethyl Sulfoxide (DMSO, empirically C2H6OS), also known as methyl sulfoxide, dimethyl sulphoxide, dimethylsulfoxide, methylsulfinylmethane or sulfinylbismethane, is a sulfur-containing organic chemical compound. ... Methylsulfonylmethane (abbreviated MSM, chemical formula CH3SO2CH3) is a naturally occurring sulfur compound present in small amounts in many foods and beverages. ...

Any of various organic sulfur compounds having a sulfonyl group attached to two carbon atoms, especially such a compound formerly used as an antibiotic to treat leprosy, dermatitis herpetiformis, tuberculosis, or Pneumocystis Carinii Pneumonia (PCP).
