Thiophenol
Thiophenol is an aromatic organosulfur compound with formula C₆H₅SH, consisting of a benzene ring bonded to a thiol group.
Thiol: An organosulfur compound containing a carbon–sulfur–hydrogen group, written R–SH. Thiophenol is the aromatic member whose sulfur is bonded directly to a benzene ring.
Benzene: A six-carbon aromatic hydrocarbon with a planar ring of delocalized electrons. Its aromatic ring is the carbon framework of thiophenol.
Thioether: An organosulfur compound in which sulfur links two carbon groups, written R–S–R′. Alkylation of thiophenolate provides a direct route to aryl thioethers.
Phenol: An aromatic compound with formula C₆H₅OH, consisting of a benzene ring bonded to a hydroxyl group. Replacing oxygen in phenol with sulfur changes acidity, bonding, and oxidation chemistry.
Thiophenolate: The conjugate base of thiophenol, formed by loss of its sulfur-bound proton. Deprotonation creates the nucleophile used in many thiophenol reactions.
Aromaticity: The unusual stability of cyclic, conjugated molecules with delocalized π electrons. Aromatic stabilization distinguishes thiophenol’s ring from an ordinary alkene framework.
Aryl sulfide: An organosulfur compound in which an aromatic carbon is bonded to a sulfide sulfur. Thiophenol is a common starting material for making aryl sulfides.
Benzyl mercaptan: An aromatic-containing thiol with formula C₆H₅CH₂SH, also called benzylthiol. Its sulfur is separated from the aromatic ring by a carbon, unlike thiophenol.
Disulfide: A compound containing a sulfur–sulfur single bond, commonly written R–S–S–R. Oxidation couples two thiophenol molecules into diphenyl disulfide.
Sulfur: A chemical element with symbol S and atomic number 16. Sulfur supplies the thiol group and gives thiophenol its characteristic reactivity.
