Hydroboration Oxidation of Alkenes

Share This Post

Hydroboration-oxidation is yet another alcohol yielding alkene reaction. However this reaction results in an alcohol adding to the less substituted carbon for an anti-Markovnikov product.

The video below helps you understand the reactivity of Boron as well as the hydroboration and oxidation steps of the reaction mechanism.

  1. What is the final product than that we normally need to show? Still a bit confused…

  2. When alkyl group is kicked by B then why does it attacks the Oxygen bound to B and not the other oxygen?

  3. Thank you for the video, amazing explanation. I do have a question though, if we are in a basic solution and it is okay to have OH-, and it was reactive earlier on and attacked the Boron when it was linked to 3 O_R, does OH- at the end continue to break and form bonds with B(OH)3?

  4. This video helped a lot. Thank You

    thanks for this video..even it is a little tricky but its okay Ive already got an idea from this video. 🙂
