In organic chemistry, an organic sulfide (British English sulphide) or thioether is an organosulfur functional group with the connectivity R−S−R' as shown on right. Like many other sulfur-containing compounds, volatile sulfides have foul odors. A sulfide is similar to an ether except that it contains a sulfur atom in place … See more Sulfides are sometimes called thioethers, especially in the old literature. The two organic substituents are indicated by the prefixes. (CH3)2S is called dimethylsulfide. Some sulfides are named by modifying the common name for … See more Sulfide is an angular functional group, the C–S–C angle approaching 90° The C–S bonds are about 180 pm. For the prototype, dimethylsulfide, the C-S-C angles is 99°, which is smaller than the C-O-C angle in ether (~110°). The C-S distance in … See more Oxidation While, in general, ethers are non-oxidizable at the oxygen, sulfides can be easily oxidized to sulfoxides (R−S(=O)−R), which can themselves be … See more Sulfides are important in biology, notably in the amino acid methionine and the cofactor biotin. Petroleum contains many organosulfur compounds, including sulfides. See more Sulfides are typically prepared by alkylation of thiols: Such reactions are usually conducted in the presence of a … See more WebThis thioether bond structure (C–S–C) in sulfur-doped carbon can be disassembled by the assistance of “voltage-scissors” in the low voltage range of 0.01–0.50 V vs. Na/Na +. The small sulfur species derived from the thioether bond structure react with the sodium anode to form insoluble sulfides.

Unlike ethers, thioethers occasionally serve as bridging ligands. The complexes Nb2Cl6(SMe2)3 is one such example. It adopts a face-sharing bioctahedral structure with a Nb(III)=Nb(III) bond, spanned by two chloride and one dimethylsulfide ligands. The complex Pt2Me4(μ-SMe2)2 is a source of "PtMe2". WebAlcohols. An alcohol can be recognized by the presence of the hydroxy or alcohol functional group on an organic molecule. Consider the structure shown below: The oxygen and … WebStructure and properties.
