Carbonyl Condensation Reactions
The aldol reaction is a carbonyl condensation that occurs between two aldehyde or ketone molecules.
Practice this chapterThe aldol reaction is a carbonyl condensation that occurs between two aldehyde or ketone molecules. Aldol reactions are reversible, leading first to β -hydroxy aldehydes/ketones and then to α , β -unsaturated products after dehydration.
A mixed reaction can be successful, however, if one of the two partners is an unusually good donor (ethyl acetoacetate, for instance) or if it can act only as an acceptor (formaldehyde and benzaldehyde, for instance). In this chapter, we’ve discussed the fourth and last of the common carbonyl-group reactions—the carbonyl condensation.
two partners — an unusually good donor (ethyl acetoacetate, for instance) or if it can act only as an acceptor (formaldehyde and benzaldehyde, for instance). aldol reaction — a carbonyl condensation that occurs between two aldehyde or ketone molecules.
Worked example
What does “two partners” mean in Carbonyl Condensation Reactions?
- 1Use the wording this chapter gives for two partners.
- 2The book says: an unusually good donor (ethyl acetoacetate, for instance) or if it can act only as an acceptor (formaldehyde and benzaldehyde, for instance).
- 3Do not use the meaning of aldol reaction. That term means a carbonyl condensation that occurs between two aldehyde or ketone molecules.
Result: an unusually good donor (ethyl acetoacetate, for instance) or if it can act only as an acceptor (formaldehyde and benzaldehyde, for instance)
Why. That is the meaning this chapter gives for two partners.
Do not swap two partners and aldol reaction. two partners means an unusually good donor (ethyl acetoacetate, for instance) or if it can act only as an acceptor (formaldehyde and benzaldehyde, for instance). aldol reaction means a carbonyl condensation that occurs between two aldehyde or ketone molecules.
