Alkenes with a thiol group on both sides of the double bond are called enedithiols.
These materials exist as "cis" or "trans" isomers depending on the geometry of the double bond.
The aldehydic carbon-oxygen double bond can also be subject to hydroformylation, which leads to formic acid and its esters.
Due to the nature of elimination, it can be applied to both small rings, and large rings containing a double bond.
The overall transformation is the conversion of the carbonsulfur bonds to a carboncarbon double bond.
Oxidation at the double bond occurs slowly in air, and is known as rancidification in foodstuffs or drying in coatings.
Each double bond has two additional localized electrons, while each triple bond has four additional electrons (two pairs) between the bonded atoms.
The compound is deprotonated on one side and protonated on another side, whereas a single bond and a double bond are exchanged.
