Webenolate anion is in equilibrium with free acetone as the pKa of acetone is 19.3 and NaOH is not a sufficiently strong enough base to ensure complete deprotonation. However, as benzaldehyde is a more reactive electrophile than acetone, the enolate will selectively act as a nucleophile towards it, forming a β-hydroxyketone intermediate. Both of ...
Webacidic to react with the enolate of cyclopentanone (pKa ~ 20). How can we fix it? Putting a protecting group on the alcohol is the easiest way to solve the problem. Reaction 1.3: Here we’re generating a strong base (a Grignard reagent) in the presence of an acidic functional group (a phenol; pKa ~ 10). WebThe p K a of cyclopentane is > 60, which is about what is expected for a hydrogen that is bonded to an sp3 carbon. Explain why cyclopentadiene is a much stronger acid (p K a=15), even though it too involves the loss of a proton from an sp3 carbon.
