DiBAl-H Reduction Reaction of Ester or Nitrile to Aldehyde

Leah4sci.com/redox presents: DiBAl or DiBAl-H Reduction Reaction for converting Esters and Nitrile to Aldehydes using Diisobutylaluminum Hydride
Need help with orgo? Download my free guide '10 Secrets to Acing Organic Chemistry' HERE: leah4sci.com/or...
This video breaks down the reducing agent DiBAl to help you understand its reactivity with Esters and Nitriles for a partial reduction to form an Aldehyde
This is video 9 in the Organic Chemistry Oxidation/Reduction video series. Catch the entire series along with my redox practice quiz and cheat sheet on my website: leah4sci.com/redox
Note: At 2:41, I incorrectly state that LiAlH4 will reduce a nitrile all the way to a primary alcohol. Instead, LiAlH4 reduces a nitrile all the way to a primary amine.

Correction: LAH will reduce a nitrile all the way down a primary amine (not to an alcohol)

[@Leah4sci]

Great catch! You are right. LAH will reduce a nitrile all the way to a primary amine (not an alcohol). We have added a note to the video’s description to address this error. Thank you!

Thanks!
I can use this information for my experiment

[@Leah4sci]

Awesome!

[@dibakarrajbongshi9215]

how is the aluminium cut off

[@twishumtahacs7485]

The lone pair of the oxygen atom in water attacks the aluminium, thus breaking the sigma bond between Al and the oxygen atom of the substrate. Now those two electrons participate in sigma bond formation between the O atom and the carbon atom of the substrate. The bond between C and OEt is again broken up. OEt leaves as OEt-. Again OEt- captures the H+ atom from water to form EtOh. Thus aluminium is cut off.

Super explanation mam

[@Leah4sci]

Glad you liked it!

[@Yujigillsbig]

Thank you so much for your explanation. However, I was wondering, what would happen if nitrile and ester are present on the same molecule? Will only one be reduced if the number of equivalents are not specified?

[@Leah4sci]

Great question! Unfortunately, I don't offer tutoring over social media. For help with questions like this and more, I recommend joining the organic chemistry study hall. Details: leah4sci.com/join or contact me through my website leah4sci.com/contact/
