The hydration reaction is an addition of water across a -bond. When hydration is carried out on an alkyne, water is added to only one -bond to form an enol. Most enols are relatively unstable and equilibrate to a more stable carbonyl form through a process called tautomerization. Acid catalyzed hydration is a Markovnikov addition, and the ...

Alkyne 1,4-addition to less electrophilic substrates can be carried out at elevated temperatures. Unfortunately alkyne dimerization is a common side reaction, which can be avoided using very bulky and electron-rich phosphine ligands. Hayashi JACS 2008, 130, 1576.
