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]
Geminal dithiols have the formula RR'C(SH) 2. They are formally derived from aldehydes and ketones by the action of hydrogen sulfide. [1] Their stability contrasts with the rarity of geminal diols. Examples include methanedithiol, ethane-1,1-dithiol, and cyclohexane-1,1-dithiol.
1,4-Dithiane is an organosulfur compound with the formula (SC 2 H 4) 2. It is one of three isomers of the formula (CH 2) 4 S 2. The 1,4-isomer, a bisthioether, arises by the alkylation of 1,2-ethanedithiol with 1,2-dibromoethane. It has no applications but traces occur as a product of degradations, e.g., cooking [3] coal pyrolysis. [4]

In organosulfur chemistry, a 1,2-dithiole is a type of heterocycle. The parent of this class of compounds is 1,2-dithiacyclopentene. The anticancer drug oltipraz is a dithiole. [1] The drug Oltipraz features a 1,2-dithiole ring.
Adjusting these figures, in the grey powder there is about 13.5 g of oxygen for every 100 g of tin, and in the white powder there is about 27 g of oxygen for every 100 g of tin. 13.5 and 27 form a ratio of 1:2. These compounds are known today as tin(II) oxide (SnO) and tin(IV) oxide (SnO 2). In Dalton's terminology, a "protoxide" is a molecule ...
