**Pharmaceutical Synthesis Case**: In the synthesis of a novel anti - cancer drug, 1,5 - Cyclooctadiene was used as a key intermediate. First, it underwent a Diels - Alder reaction with a specific dienophile. The reaction was carried out in an anhydrous ether solution at a temperature of 50 °C for 24 hours in the presence of a Lewis acid catalyst. After purification, the resulting cyclic compound was further modified through a series of chemical reactions, including oxidation and amination, to form the final anti - cancer drug. This application demonstrated the importance of 1,5 - Cyclooctadiene in the development of new pharmaceuticals.
**Polymer Production Case**: A research team aimed to produce a flexible copolymer with improved reactivity. They used 1,5 - Cyclooctadiene as one of the monomers. The polymerization was carried out in a bulk polymerization process at 80 °C using a free - radical initiator. The resulting copolymer had excellent flexibility, which made it suitable for applications in flexible electronics. The unique structure of 1,5 - Cyclooctadiene contributed to the special properties of the copolymer, such as its ability to form cross - links under certain conditions.
