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.

WebMethanethiol (also called methyl mercaptan), has the formula CH 3 SH. Ethanethiol (ethyl mercaptan) is the most common odorant for liquid propane (LP) gas. The mild oxidation of thiols gives compounds called disulfides. The amino acids cysteine [HSCH 2 CH (NH 2 )COOH] and methionine [CH 3 SCH 2 CH 2 CH (NH 2 )COOH] (Figure 3.5. 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.
Thiols 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 … See more In organic chemistry, a thiol , or thiol derivative, is any organosulfur compound of the form R−SH, where R represents an alkyl or other organic substituent. The −SH functional group itself is referred to as either a thiol group … See more Thiols having the structure R−SH, in which an alkyl group (R) is attached to a sulfhydryl group (SH), are referred to as alkanethiols or alkyl thiols.
