Alkynol

Some alkynols play a role as intermediates in the chemical industry.

The shortened term ynol typically refers to alkynols with the hydroxyl group affixed to one of the two carbon atoms composing the triple bond (C≡C−OH), the triple-bond analogues to enols.

The deprotonated anions of ynols are known as ynolates, the triple-bond analogues to enolates.

Alkynols may be formed by the alkynylation of carbonyl compounds, usually in liquid ammonia.

[2] Ynolates are chemical compounds with a negatively charged oxygen atom attached to an alkyne functionality.
