Carbonyl Condensation Reactions The Aldol Reaction Recall that the characteristic reaction of aldehydes and ketones is nucleophilic addition. An aldol reaction is a nucleophilic addition in which an enolate is the nucleophile. Figure 24.1 The aldol reaction An example of nucleophilic addition 2
Carbonyl Condensation Reactions The Aldol Reaction A second example of an aldol reaction is shown with propanal as the starting material. The two molecules of the aldehyde that participate in the aldol reaction react in opposite ways. 3
