Jeremy, thanks a ton, man! I've since made a second video on this topic kzread.info/dash/bejne/gp160rZritvdmNo.html (I go a bit more in depth because you can get a different double bond if you have a ylide thats attached next door to an aromatic system). Make sure to check out joechem.io/videos/38 where I have a worksheet + solutions linked (literally for free). And if you subscribe that would be H U G E L Y appreciated :)

This channel is awesome!!!

hi you know for the lda how it deprotonates less sterically hindered alpha hydrogens why did it deprotonate the sterically hindered alpha H's

why not just use NaOme if you deprotonated the least sterically hindered H's

It does because LDA is VERY large, so it is hard to reach more "crowded" alpha H's. So it is lazy and opts for alpha H's that are less sterically hindered, aka more accessible. Something like NaOMe is MUCH smaller, so it can access more "crowded" alpha H's.

Je ne suis pas d’accord avec ta réaction mon type
