Pericyclic Reactions Part 1: Revisiting the Diels-Alder Reaction

An important class of reactions is the pericyclic reactions. We've been introduced to one subclass of these, cycloaddition reactions, when we looked at the Diels-Alder reaction. For the next few tutorials we will learn about some other important pericyclic reactions, but let's start by refreshing out memory with that first classic reaction.

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

You are the best professor, I don’t know why I am here, I am in grade 9 and don’t understand a thing but thank you for the hundreds of people you are helping.

Haven't done this since uni! Was explaining this to an alevel student of mine and was sad to find out I couldn't remember a lot of it... thanks for the refresher!

[PunmasterSTP]

Thanks for letting us know the diel with these reactions!

[joelchristophr]

Great explanation thankyou so much master... but I have one doubt... in 7:01 time of this video, you told preference will be to end up adjacent in the product why is it so could you please explain 🙏🙏🙏🙏🙏🙏🙏

[sharvarimahajan]

Thank you thank you thank you....it helped me so much with my chem class 🙏🙏🙏

[bloo]

Thank you so much for making these. They must be a waste of time from your end, but they really help stupid undergrads like me..

Thank you for the great explanations! At the bottom left of the slide at 4:13, wouldn’t the 0-node MO of dienophile be in a higher energy than the 0-node MO of the diene (assuming upwards direction <-> increasing energy), since the 0-node MO of diene is stabilized by delocalization?

Thanks a lot Professor Dave. you help me a lot

Hey Dave.
I know u did a video on scientific method called "Why you should never say 'its just a theory'", but could you perhaps do a video on inductive method vs deductive method?
I find it hard, at times, to differentiate between the two, aswell as explain why i chose one over the other when writing papers.
Thanks for the content!

Can you plzz name each reagent, substrate & products in all videos....

[Niu]

make me feel stupid which is a humbling expirience.

I'm not an english user. So I'm so sorry about my grammer is bad. I wonder the meaning of p obital's color? One is colored and the other one is not colored.

Please leave the bottom 15% of your slides blank, as this section is being obscured by the subtitles.

My favorite reaction since i learned about this, and i dont know the reason why 😃😆
And yes, thank you 🙏 for explaining it in deep
Sir, pls tell any more example which behave like the Ome and Co2me one.
