Question
Chapter 13, Problem 46P
Interpretation Introduction
Interpretation: The mechanism for the given aldol addition reaction has to be proposed.
Concept introduction:
If two different carbonyl compound used in an aldol addition, known as a crossed-aldol reaction. If the two carbonyl compounds contain alpha carbon then four products are formed because two different enolate ion is formed.
One product can be formed from crossed-aldol addition reaction if one of the carbonyl compounds does not have any alpha hydrogen and therefore cannot form an enolate ion.
