Lab 5: DielsAlder Reaction The laboratory procedure used was written by Dr. John Barbaro of Rocky Mountain College. The DielsAlder reaction is a well known example of cycloaddition chemistry. The evidence from the qualitative testing performed in the laboratory confirms the formation of sixmembered rings by cycloaddition, also known as a DielsAlder reaction.
The melting point analysis shows that the product of the DielsAlder reaction was somewhat impure, but the product of the hydrolysis of the DielsAlder adduct was very pure.
