Chapter 23 ● α carbon of a carbonyl carbon acting as a nucleophile ● Rest of reactions we see will go through enol or enolate from ● Aldehydes and Ketones exist in equilibrium between keto and enol forms 1,3 – dicarbonyls enol is favored ● Note review acid and base catalyzed ,mechanism of ketone – enol tautomerization ch.11 Reactivity of enols o C=C is electron rich and can act as a nucleophile Enolates are formed by deportation of α carbon Pka values of α H+ Aldehyde or Ketone Consider bases for Base Conj. Acid Pka Na+ -OH H2O 15.7 ● Equilibrium favors acid with higher Pka Enols and Enolates
