In today's experiment you will synthesize the a,ß-unsaturated ketone from 3- nitrobenzaldehyde and acetophenone via an aldol condensation. Once the aldol product forms, the reaction spontaneously dehydrates to the conjugated enone. This reaction fulfills some of the principles of green chemistry in that it has high atom economy, produces water as the only major byproduct, and uses ethanol as a non-toxic solvent.
