This video shows you the reaction and mechanism for the oxymercuration of alkynes, in which an alkyne reacts with a mercuric ion catalyst to form a ketone product at the more substituted position, following Markovnikov’s rule.
You’ll learn the step-by-step alkyne oxymercuration mechanism, including Keto Enol Tautomerization to isomerize an unstable enol intermediate.
And finally you’ll learn about the regioselectivity when starting with an asymmetrical alkyne
