WebThey undergo the electrophilic additions like halogenation and hydrohalogenation. They can also be reduced with the aid of a heterogeneous catalyst or oxidized via several techniques. Alkynes do, however, have a number of unique reactions that you’re not going to see with other functional groups. Catalytic Hydrogenation of Alkynes WebSo that's adding my H20 across my triple bond. And then there was still a hydrogen on this carbon on the right like that. So that's my enol intermediate like that. So let's take a look at what's going to happen to that enol intermediate. It's going to rearrange. And on the last video, we saw an acid-catalyzed tautomerizaton. WebWater can be added to the triple bond. Although the reaction can be catalyzed by a strong acid, it is faster, and yields are higher, when a combination of dilute acid and mercuric ion (Hg2!) catalysts is used. The addition of water to a triple bond, like the corresponding addition to a double bond, is called hydration. screw ring gauge
