Aldol condensation reaction summary - ANS combination of two aldehyde or ketone
molecules with the loss of water through elimination.
An electron rich alpha carbon atom of an enolizable aldehyde or ketone molecules attacks the
electron poor carbonyl carbon of the second aldehyde or ketone molecule through nucleophilic
addition.
Can be catalyzed by an acid or base
aldol condensation reagents - ANS needs a strong base for high conc. of enolates.
8 M of NaOH or 33% NaOH is catalytic enough
Bases used but produce low conc. of enolates; NaOH or KOH
aldol condensation intermediate step - ANS alpha-hydroxyaldehyde or alpha-hydroxyketone
-may not happen if aryl group present at the end of the ketone because dehydration happens
more readily.
