This video shows you the reaction and mechanism for the hydroboration oxidation of alkynes, in which an alkyne reacts with a boron-containing reagent, followed by NaOH and H2O2, to form either an aldehyde or ketone product at the less substituted, anti-Markovnikov position.
You’ll learn the step-by-step alkyne hydroboration oxidation mechanism, including Keto Enol Tautomerization to isomerize an unstable enol intermediate in a basic environment.
Finally you’ll learn about the regioselectivity of the reaction and compare the products when starting with terminal, symmetric or asymmetric internal alkynes.

I want to express my deepest gratitude for the invaluable help your videos provided me with. As a returning student after many years, I found myself struggling to keep up with my organic chemistry course. However, your videos have been a lifesaver, and I am thrilled to report that I just took the final exam and received a 77%. Although I believe that if I had discovered your videos earlier in the semester, I could have earned an A, I am still immensely grateful for your help. Thank you for your dedication and commitment to helping students like me succeed.

In the last compound, which is the major product ; 2 pentanone or 3 pentanone?
@Leah4sci Жыл бұрын
It should produce a racemic mixture of both compounds, where neither is considered the major product. In other words, a 50/50 mixture.

I'm sorry, but the Alkyne Practice Quiz has not been published. I don't have a firm date as to when that will be made available. I create free content as I have time, and this is one of those projects still in the works.

this is her teaching the topic. she probably has done her studies in chem so you can't ask her what materials she is using. the fact she is able to teach us in a concise way means she has learned this stuff to teach us. you can always learn from her, from other videos, and materials to teach as well
