Identification of a Conjugated Diene from Eucalyptus Oil Introduction: When two carbon-carbon double bonds are positioned next to one another‚ a conjugated diene is formed. Conjugated dienes undergo a cycloaddition reaction with certain double bonds to afford cyclohexenes and related compounds. The reaction is named Diels-Alder. The Diels-Alder reaction is between 1‚3-butadiene and ethylene to produce cyclohexene + dienedienophile. The mechanism of the Diels-Alder reaction is classified as a
