Balanced Reactions: The Diels-Alder reaction is a cycloaddition of an e-rich diene and an e- poor dienophile (alkene or alkyne). The dienophile is N-phenylmaleimide and the diene is 1,3-cyclohexadiene in s-cis formation and will undergo concerted syn addition to form the diels-alder product. i Mechanism: Results and Discussions: 1.00g of N-phenylmaleimide was added to 8.0ml of ethyl acetate and .6ml of 1,3 cyclohexadiene in 5.0ml ethyl acetate was added to the mixture and let sit for a week. The crystals obtained were dried, weighed,
