Self aldol condensation of acetone
WebApr 7, 2024 · In this experiment to synthesize dibenzalacetone, the Claisen-Schmidt condensation, a crossed aldol condensation, was used. The Claisen-Schmidt condensation requires a ketone enolate, such as acetone, and an aldehyde that acts as the electrophile, unlike the self-aldol condensation reaction. WebA crossed aldol condensation between acetophenone and piyalaldehyde is shown below. Notice that acetophenone has only one alpha carbon (three acidic hydrogen atoms) …
