Question

1. Explain the principal synthetic value of the Diels-Alder reaction.

2. What is the product expected from the reaction of 1,3-butadiene and 3-

sulfolene?

3. a. Find the chemical structure of aldrin.

b. Do a literature search to find out more about the toxicity of insecticides

such as aldrin. Suggest a reason that the insecticide Aldrin accumulates in

animal tissue.

Answer 1

1. The special thing about diels-alder reaction is that it is a useful reaction to form carbon-carbon bonds. Secondly, it ia a highly regioselective reaction. Thirdly, its mechanism is easy to understand as it is concerted.

2)

Aldrin was used as an organo-chlorine insecticide. It is able to bio accumulate due to its long half life and causes serious health issue.
