The reaction is yielding 90%.
I believe the hydrogen on C1 is more acidic compared to other hydrogens on C 2/3/5. Am I right? Can anyone explain why so (or is this too complex)?
If above is the case then enolate would prefer ethyl in methyl ethyl ketone. Would it contradict with carbanion stability (since they prefer CH3>1>2>3) ?
Probably, I am thinking too much and confusing myself. Any help appreciated.
