WebThiols are the sulfur analogue of alcohols (that is, sulfur takes the place of oxygen in the hydroxyl ( −OH) group of an alcohol), and the word is a blend of " thio- " with "alcohol". Many thiols have strong odors resembling that of garlic or rotten eggs. Thiols are used as odorants to assist in the detection of natural gas (which in pure ... WebThe redox reaction of thiol is mentioned below. 2 R–SH + Br 2 → R–S–S–R + 2 HBr. Reagents such as hydrogen peroxide or sodium hypochlorite can also produce sulfonic acids. R–SH + 3 H 2 O 2 → RSO 3 H + 3 H 2 O. In the presence of a catalyst, oxidation can be affected by oxygen. 2 R–SH + 1 ⁄ 2 O 2 → RS–SR + H 2 O.

WebOxidation of Thiols. In alcohols, oxidation generally occurs at the carbon bonded to oxygen. In contrast, with thiols the oxidation site is often at the sulfur. For example, many oxidizing agents (even molecular oxygen in air) oxidize thiols to disulfides. The reverse reaction is also readily accomplished using a reducing agent such as Zn/HCl.
