Diels-Alder Cycloaddition

The mechanism and stereochemistry of the Diels-Alder reaction are examined here. This cycloaddition is one of the coolest reactions in organic chemistry. You'll see.

Check out "Is This Wi-Fi Organic?", my book on disarming pseudoscience!

In middle school we were all singing along to the bill nye intro, now in college we sing along to the professor dave intro xD

This is great! Thanks for including the MO and explaining EVERYTHING to do with it instead of just the mechanism; it was so helpful.

You know you like Professor Dave when you sing along to his song :)

PROFESSOR DAVE YOU'RE AWESOME! my professor at Colorado State tries explaining everything with resonance and partial charges but you made this so much simpler and comprehensive! READY TO CRUSH MY O CHEM FINAL. THANK YOU

[sccm]

He knows a lot about the science stuff. Professor Dave explains! wohoo

I´m so glad I found your channel. If you ever want to come and teach Chemistry in Costa Rica I´ll find a way to get rid of my crappy professor and you can fill the spot. Thank you so much for making the video! I have a presentation tomorrow on Diels Alder Cycloaddition and I´m sure with your help I´m gonna rock :)

I sudy molecular Biomedicine in Germany and your Vides help me so much!! Thanks alot.

There is always a video, that can teach everything in 5 minutes. Thank you.

Thank you very much for this professor! I've been trying to understand the stereochemistry of this reaction for months and now everything is clear thanks to you!

[jhopeswoundofglory]

Thank you so much! I learned more in about 9 mins than I did in an hour of my orgo chem class :D

[dkastner]

You are the best Organic Chemistry teacher on the internet, literally! I just wanted you to know. Anyways, I would also like to see a video explaining the MO theory a little more, but extremely well done:) Thanks!

Its video is the first i have seen by the Professor Dave, and i have to say... The intro is so precious for this dirty world! \°~°/

[ishagaur]

I'm from India and i loved the way u explain thank u so much for this

[brim]

Its that time of the year!!! Appreciate the videos... You're an absolute lifesaver

[orangesharpy]

Thanks Dave! your explanations are really really good.

[Paraselene_Tao]

Wow. We didn't go over this is a college level o-chem class, but it's very cool. Thank you.

[mattlarsen]

Holy shit. You explained this so much better than my professor.

I have seen this done with the diene being labeled 1-4 and the dienophile being labeled A & B, it creates less confusion on big rings. Thanks for your videos!

[hamadkadventures]

Thank you professor Dave, that was an amazing explanation. :)

My O-chem book butchered and overcomplicated it's explanation of endo and exo. THANK YOU for knowing exactly how to explain it. I want to find whoever made my book and fight them.

2 pages! TWO FULL PAGES to explain endo and exo. Listen to this "In the Endo approach, the dienophile aligns with its electron withdrawing group substituent underneath the pi system or directly above it. When it reacts such that the pi electron orbitals of its electron withdrawing group align under (or above) the pi orbitals of the diene, the orientation of approach is called endo." and it carries on like this
