and are among the alcohols. Thus, as structural features, they have a C≡C triple bond and a hydroxy group. They are not identical to the

ynol In organic chemistry, an alkynol (shortened to ynol) is an alkyne with a hydroxyl group affixed to one of the two carbon atoms composing the triple bond (). The deprotonated anions of ynols are known as '' ynolates''. An ynol with hydroxyl gro ...

s. Some alkynols play a role as intermediates in the chemical industry. Compounds in this group include propargyl alcohol, 3-butyn-1-ol, and 5-hexyn-1-ol.

Synthesis

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