Protecting group - Wikipedia

WebA disulfide is a compound containing an -S-S- linkage. (Organic) sulfides have the structure R-S-R′, and are therefore the sulfur analogues of ethers. The nomenclature of sulfides can be easily understood if one understands the nomenclature of the corresponding ethers. Notice that the term “thio” is also used in inorganic chemistry. WebSelf-assembled monolayers (SAMs) of thiols are prepared by immersing a clean gold substrate into a dilute solution of the desired thiol. Figure 1. Schematic showing an ordered self-assembled monolayer of densely packed alkane thiols.

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. brewstew tropes
