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.
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]
Propane-1,3-dithiol is the parent member of this series. It is employed as a reagent in organic chemistry, since it forms 1,3- dithianes upon treatment with ketones and aldehydes . When derived from aldehydes, the methyne ( =CH− ) group is sufficiently acidic that it can be deprotonated and the resulting anion can be C-alkylated .
