In organic chemistry, a thiol (/ ˈ θ aɪ ɒ l /; [1] from Ancient Greek θεῖον (theion) ' sulfur ' [2]), or thiol derivative, is any organosulfur compound of the form R−SH, where R represents an alkyl or other organic substituent.

Thiols are usually prepared by using the hydrosulfide anion (-SH) as a nucleophile in an S N 2 reaction with alkyl halides. One problem with this reaction is that the thiol product can deprotonate and undergo a second S N 2 reaction with an additional alkyl halide to produce a …

Thiols are usually prepared by using the hydrosulfide anion (-SH) as a neucleophile in an S N 2 reaction with alkyl halides. On problem with this reaction is that the thiol product can undergo a second S N 2 reaction with an additional alkyl halide to produce a sulfide side product.

Jul 5, 2015 · Thiols and Thioethers: Properties and Key Reactions. If you can get beyond their foul smells, thiols have a lot of similar characteristics to alcohols! Like alcohols, they can be deprotonated with base and undergo S N 2 reactions with alkyl halides to …

Feb 28, 2024 · A thiol, in its most fundamental definition, is a chemical compound characterized by the presence of a sulfhydryl group (-SH). This molecular arrangement comprises a sulfur atom bonded to a hydrogen atom. Thiols are often referred to as mercaptans due to their ability to capture (or bind) mercury compounds.

Treatment of a thiol with a base, such as NaH, gives the corresponding thiolate ion (RS –), which undergoes reaction with a primary or secondary alkyl halide to give a sulfide. The reaction occurs by an S N 2 mechanism, analogous to the Williamson synthesis of ethers (Section 18.2).

Sep 30, 2024 · Treatment of a thiol with a base, such as NaH, gives the corresponding thiolate ion (RS –), which undergoes reaction with a primary or secondary alkyl halide to give a sulfide. The reaction occurs by an S N 2 mechanism, analogous to …

Thiols can be defined as a sulfur analogue of alcohols. In a simpler way, it is an organic compound consisting of compounds with a sulfur atom. It is also referred to as mercaptan. It consists of sulfhydryl group, i.e., Thiol = R-SH.

Thiol, any of a class of organic chemical compounds similar to the alcohols and phenols but containing a sulfur atom in place of the oxygen atom. Thiols are among the odorous principles in the scent of skunks and of freshly chopped onions; their presence in petroleum and natural gas is.

The conjugate base of thiols is the thiolate ion (mercaptides) which has a negative charge on sulfur, and it is delocalizing the charge more efficiently than oxygen does in the alkoxide ion. So, thiols have lower pKa than alcohols which is to say that thiols are stronger acids than alcohols.
