WebThiols, which are also called mercaptans, are analogous to alcohols. They are named in a similar fashion as alcohols except the suffix -thiol is used in place of -ol. By itself the -SH group is called a mercapto group. Thiols are usually prepared by using the hydrosulfide anion (-SH) as a neucleophile in an S N 2 reaction with alkyl halides. WebJul 20, 2024 · 15.7: Redox Reactions of Thiols and Disulfides. A disulfide bond is a sulfur-sulfur bond, usually formed from two free thiol groups. The interconversion between dithiol and disulfide groups is a redox reaction: the free dithiol form is in the reduced state, and the disulfide form is in the oxidized state. Notice that in the oxidized (disulfide ...
