Thiol with a blue highlighted sulfhydryl group.. In organic chemistry, a thiol (/ ˈ θ aɪ ɒ l /; [1] from Ancient Greek θεῖον (theion) 'sulfur' [2]), or thiol derivative, is any organosulfur compound of the form R−SH, where R represents an alkyl or other organic substituent.
Some sulfides are named by modifying the common name for the corresponding ether. For example, C 6 H 5 SCH 3 is methyl phenyl sulfide, but is more commonly called thioanisole, since its structure is related to that for anisole, C 6 H 5 OCH 3. The modern systematic nomenclature in chemistry for the trival name thioether is sulfane. [2]

Thiophenol is an organosulfur compound with the formula C 6 H 5 SH, sometimes abbreviated as PhSH. This foul-smelling colorless liquid is the simplest aromatic thiol.The chemical structures of thiophenol and its derivatives are analogous to phenols, where the oxygen atom in the hydroxyl group (-OH) bonded to the aromatic ring in phenol is replaced by a sulfur atom.
Some metal sulfides, when exposed to a strong mineral acid, including gastric acids, will release toxic hydrogen sulfide. Organic sulfides are highly flammable. When a sulfide burns it produces sulfur dioxide (SO 2) gas. Hydrogen sulfide, some of its salts, and almost all organic sulfides have a strong and putrid stench; rotting biomass ...

Propanethiol is an organic compound with the molecular formula C 3 H 8 S. It belongs to the group of thiols.It is a colorless liquid with a strong, offensive odor. It is moderately toxic and is less dense than water and slightly soluble in water.
Thioesters can be prepared by condensation of thiols and carboxylic acids in the presence of dehydrating agents: [2] [3] RSH + R'CO 2 H → RSC(O)R' + H 2 O. A typical dehydration agent is DCC. [4] Efforts to improve the sustainability of thioester synthesis have also been reported utilising safer coupling reagent T3P and greener solvent ...
