Stevens Rearrangement (Nitrogen Ylides)

[@MOHIT-vr3zn]

Great video not like many youtuber who focus only on tricks

[@preetisoni6083]

Keep it up sir You’re awesome You deserve millions of subscribers Whenever people came to know that how to study chemistry then they will hit at this channel I am pretty sure

[@sawankumar6795]

Very helpful Well explained..

[@ChemoSpecific]

Glad it was helpful!

[@jaggu3149]

Thank you sir

[@prabhu3354]

Superb teaching sir... why? In question 4. the 2,3 Stevens rearrangement is not possible.. same as question 3

[@ChemoSpecific]

It is 2,3 Stevens rearrangement in question no 4

[@prabhu3354]

@@ChemoSpecific thank you sir...

[@kanchithalaivanselvaraj8996]

In the [2,3] Steven’s rearrangement, how a nucleophic carbanion attacks the double which is also rich in electron density. Why not [1,2], because of near quaternary nitrogen

[@sivaskumarb7664]

acyclic nitrogen is more basic than the cyclic one (also steric).

Plz Sir,coupling reaction ka concept clear kra dijiye .

Thanks a lot ,sir

Sir ,according to Baldwin's rule 3_endo tet reaction are not flavoured then how this mechanism can be correct although it looks fine?

[@ChemoSpecific]

Steric and electronic factors modifies the Baldwin rules at times. 3-endo-Tet reaction should be disfavored. Such reactions do not form a ring, but appear to pass through a cyclic transition state leading to the cleavage of a sigma bond, while a new sigma bond is formed. I hope you understand why it happens

Sir 9.30pr jb anion form hua to yha stereo retain kaise rhi bcoz resonance mai jane pr anion wedge se desh mai bhi convert ho sakta hai .

[@ChemoSpecific]

It follows solvent cage mechanism. As a result the intermediate retains its memory of stereochemistry.

[@MOHIT-vr3zn]

12 30 pr 2 3 sigmatropic bhi to ho sakti hai

[@ChemoSpecific]

Product would have been same in both the cases. You are right. (2,3)-sigmatropic rearrangement possible
