Acetylide
 | The English used in this article or section may not be easy for everybody to understand. (September 2025) |
Acetylide, also known as ethynide, dicarbide, and percarbide, is an ion. Its chemical formula is C2−2. It is made by deprotonation of acetylene. Some are known as carbides. Copper(I) acetylide is an example.
In organic chemistry
In organic chemistry, acetylide means the functional group −C≡C−. This group is made by deprotonation of a terminal alkyne, −C≡CH. Alkynes are more acidic than alkanes or alkenes. This means acetylides can be made with strong but common bases like sodium amide.
Safety
Some acetylides (chemical compounds that contain acetylide ions) are explosive.
