Aldol and Claisen Condensation Paths

Description

Aldol condensation and Claisen condensation are two carbonyl reactions that begin in a similar way but end with different products. Aldol condensation can happen with aldehydes or ketones and is acid- or base-catalyzed. Claisen condensation is a base-promoted reaction between ester molecules that forms a β-ketoester.

Transcript

Die Aldol-Kondensation findet zwischen Aldehyden oder Ketonen statt, um α,ꞵ-ungesättigte Carbonylverbindungen zu erhalten, während die Claisen-Kondensation zwischen zwei Estermolekülen stattfindet, um einen ꞵ-Ketoester zu erzeugen.

Die Aldol-Kondensation findet unter sauren und basischen Bedingungen statt, während die Claisen-Kondensation...
