WebThe Claisen condensation reaction is an organic coupling reaction that results in the formation of a C-C bond between either a single ester and one carbonyl compound or between two esters. The reaction proceeds when … Web1. Aldehydes and ketones having at least one α-hydrogen can undergo Aldol condensation reaction. 2. In the presence of dilute alkali as catalyst, aldehydes and ketones form α-hydroxy aldehydes (aldol) or α-hydroxyketones (ketol) as product. 3. When aldol condensation is carried out using same aldehyde or ketone, it is called Self-aldol …
WebIntramolecular aldol reaction is the condensation reaction of two aldehyde groups or ketone groups in the same molecule. Five- or six-membered α, β -unsaturated ketone or aldehydes are formed as products. This reaction is an important approach to the formation of carbon-carbon bonds in organic molecules containing ring systems.
