Diels-Alder Rnx: Reaction of cyclopentadiene with maleic anhydride
Why do we have to redissolve the product we get from the reaction of cyclopentadiene with maleic anhydride? Is it to remove the impurities? The endo-norbornene-5,6-cis-dicarboxylic anhydride product I got from the reaction after the second recrystallization had a melting point 24 degrees lower than the expected melting point. What do you think could affect the final product?
