Conjugated dienes are organic compounds that contain two double bonds separated by a single bond. This arrangement allows for the delocalization of electrons, which can enhance the stability of the molecule. Common examples of conjugated dienes include 1,3-butadiene and isoprene, both of which play significant roles in the production of synthetic rubber. The unique structure of conjugated dienes enables them to undergo various chemical reactions, such as Diels-Alder reactions, where they can react with other compounds to form cyclic structures. Their reactivity and stability make them important in both industrial applications and natural processes.
