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
@ChemoSpecific 4 года назад
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.

Superb teaching sir... why? In question 4. the 2,3 Stevens rearrangement is not possible.. same as question 3
@ChemoSpecific
@ChemoSpecific 4 года назад
It is 2,3 Stevens rearrangement in question no 4

12 30 pr 2 3 sigmatropic bhi to ho sakti hai
@ChemoSpecific
@ChemoSpecific 4 года назад
Product would have been same in both the cases. You are right. (2,3)-sigmatropic rearrangement possible

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

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