Ethane-1,2-dithiol, also known as EDT, [1] is a colorless liquid with the formula C 2 H 4 2. It has a very characteristic odor which is compared by many people to rotten cabbage . It is a common building block in organic synthesis and an excellent ligand for metal ions.
Dithioacetals generated from aldehydes and either 1,2-ethanedithiol or 1,3-propanedithiol are especially common among this class of molecules for use in organic synthesis. [ 2 ] The carbonyl carbon of an aldehyde is electrophilic and therefore susceptible to attack by nucleophiles , whereas the analogous central carbon of a dithioacetal is not ...
Geminal dithiols have the formula RR'C(SH) 2. They are derived from aldehydes and ketones by the action of hydrogen sulfide. Their stability contrasts with the rarity of geminal diols. Examples include methanedithiol, ethane-1,1-dithiol, and cyclohexane-1,1-dithiol.
The salt can be generated quantitatively by reaction with sodium hydride. [14] Ethanethiol can be oxidized to ethyl sulfonic acid, using strong oxidizing agents. Weaker oxidants, such as ferric oxide or hydrogen peroxide give the disulfide, diethyl disulfide: 2 EtSH + H 2 O 2 → EtS-SEt + 2 H 2 O. Like other thiols, it behaves comparably to ...
In the presence of oxygen, ethane-1,1-dithiol is converted to cis/trans-3,6-dimethyl-1,2,4,5-tetrathiane which has a rubbery aroma. This molecule has a ring with four sulfur atoms and two carbons, two ethane-1,1-dithiol molecules become linked at their sulfur atoms with the loss of hydrogen. [ 11 ]
Thiol with a blue highlighted sulfhydryl group.. 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.

2-Mercaptoethanol (also β-mercaptoethanol, BME, 2BME, 2-ME or β-met) is the chemical compound with the formula HOCH 2 CH 2 SH. ME or βME, as it is commonly abbreviated, is used to reduce disulfide bonds and can act as a biological antioxidant by scavenging hydroxyl radicals (amongst others).
