A student was supposed to carry an aldol reaction between benzaldehyde and acetone, WebQuestion: Identify the starting reagents needed to make the following compound by a mixed aldol condensation. KOH, CH3OH CHCCCH2CH3 H3 benzaldehyde (CsHsCH-O) and 2-pentanone O acetophenone (methyl phenyl ketone) and butanal benzaldehyde (C6H5CH-O) and 3-pentanone acetophenone (methyl phenyl ketone) and 2-butanone
WebThe aldol condensation reaction is an organic reaction introduced by Charles Wurtz, who first prepared the β-hydroxy aldehyde from acetaldehdye in 1872. 1 In an aldol condensation, an enolate ion reacts with a carbonyl compound in the presence of acid/base catalyst to form a β-hydroxy aldehyde or β-hydroxy ketone, followed by dehydration to ... WebThis two-step process is the aldol condensation and the final product of it is an ɑ, β-unsaturated carbonyl compound. The E1CB Mechanism in Aldol Condensation. Let’s sum …
