Transcribed Image Text:Experimental 6. Synthesis of dibenzalacetone
The Claisen Schmidt reaction
The Claisen-Schmidt reaction refers specifically to the synthesis of a,ß-
unsaturated ketones by the condensation of an aromatic aldehyde wilt a
ketone. As the aromatic aldehyde possesses no hydrogens a- to the carbonyl
group, it cannot undergo self-condensation but reacts readily with the ketone
present. The initial aldol adduct cannot be isolated asif dehydrates
spontaneously under the reaction conditions but thea,ß-unsaturated ketone so
produced also possesses activated hydrogensand may condense with a further
molecule of benzaldehyde. In the following experiments, conditions will be
chosen to optimize formation of the mono- and bis-adducts respectively and
they will be differentiated by their physical and spectroscopic properties. In
the first experiment the acetone is used in a large excess in order to minimize
the second condensation step. In the second experiment the benzaldehyde is
present in twofold excess and sufficient ethanol is added to the reaction
mixture to keep the initial condensation product in solution long enough to
react with a second molecule of benzaldehyde.
