8. The side reaction most often encountered in Diels-Alder syntheses is dimerization, in which the diene also acts as a dienophile. For example, butadiene can react with itself to yield 4-vinylcyclohexene as shown. Draw the structures of four possible Diels-Alder dimers of your diene. \( \alpha \)-phellandrene
