Coenzyme M, CHģ, is the precursor to methane (i.e. silver sulfide and nickel sulfide, said nuclei ing to claim 1, wherein. Organic sulfides are compounds in which a sulfur atom is covalently bonded to two organic groups. Polyphenylene sulfide is a useful high temperature plastic. Inorganic sulfides are ionic compounds containing the negatively charged sulfide ion, S 2 these compounds may be regarded as salts of the very weak acid hydrogen sulfide.
Petroleum contains many organosulfur compounds, including sulfides. Sulfides are important in biology, notably in the amino acid methionine and the cofactor biotin. Upon hydrogenation, thiophene gives tetrahydrothiophene, C 4H 8S, which indeed does behave as a typical sulfide. As a consequence, thiophene exhibits few properties expected for a sulfide – thiophene is non-nucleophilic at sulfur and, in fact, is sweet-smelling. The nonbonding electrons on sulfur are delocalized into the π-system. Because of their aromatic character, they are non-nucleophilic. Thiophenes are a special class of sulfide-containing heterocyclic compounds. Electromagnetic theory has been used to calculate the attenuation and scattering coefficients together with the spectral degree of blackness for polydisperse sulfide particles in a flame. These properties follow from the polarizability of the divalent sulfur center, which is greater than that for oxygen in ethers. In terms of their physical properties they resemble ethers, but are less volatile, higher melting, and less hydrophilic. This odor limits the applications of volatile sulfides. Sulfides are characterized by their strong odors, which are similar to thiol odor. The C-S distance in dimethylsulfide is 1.81 Å. Sulfide is an angular functional group, the C–S–C angle approaching 90° The C–S bonds are about 180 pm.įor the prototype, dimethylsulfide, the C-S-C angles is 99°, which is smaller than the C-O-C angle in ether (~110°). The modern systematic nomenclature in chemistry for the trival name thioether is sulfane. For example, C 6H 5SCH 3 is methyl phenyl sulfide, but is more commonly called thioanisole, since its structure is related to that for anisole, C 6H 5OCH 3. Some sulfides are named by modifying the common name for the corresponding ether. The two organic substituents are indicated by the prefixes. Sulfides are sometimes called thioethers, especially in the old literature.
