Webtype of reaction is named in honor of the German scientists, Otto Diels and Kurt Alder, who studied the reactions of 1,3-dienes with dienophiles to produce cycloadducts. Their research earned them the 1950 Nobel Prize in chemistry. The saturation of anhydride will be tested with bromine and Bayer tests. It will also be WebThe aldol reactions for acetaldehyde and acetone are shown as examples. Example: Aldol Reactions Aldol Reaction Mechanism Step 1: Enolate formation Step 2: Nucleophilic reaction by the enolate Step 3: Protonation Aldol Condensation: the dehydration of aldol products to synthesize α, β unsaturated carbonyls (enones)
