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.
