Unformatted text preview: 1 st experiment This lab involved two Diels-Alder reactions to form two different cyclic products. A Diels-Alder reaction in which a dienophile, or diene-loving molecule, acts as a electrophile with a conjugated diene to create a cyclohexane. The first reaction used furan, which served as the diene and the limiting reagent, and maleic anhydride, the dienophile, to produce a Diels-Alder Adduct of 7-oxonobornene derivative. One double bond of the diene began the flow of electrons by attacking the electropositive carbons of the dienophiele. These carbosn are electropositive and thus susceptible to attack because they are near electron withdrawing groups. The inner substiutends on the diene flip upwards while the dienohpile either flips upward or downward based on the side it is approaching from. The literature appearance of long, sharp clear crystals matched the observed appearance indicates a level of purity. The percent yield of the _____ was 61.43%, which is a substaintial yield. the literature a level of purity....
