In the previous two posts, we have seen that aldehydes and ketones react with primary amines, in mildly acidic conditions, forming an imine (a Schiff base). The reaction with secondary amines produces enamines:
Below are a few practice exmmples of these reactions :
Draw the mechanism for the reaction of the following ketones with a primary and a secondary amine to demonstrate the formation of the imine and enamine:
Check the following posts for a detailed mechanism of these reactions:
Predict the product for each reaction of aldehydes and ketones with amines:
