Written by Vijay In this experiment, cyclopentadiene and maleic anhydride were reacted in solution to produce a single organic product in crystal form. Cyclopentadiene is composed of a five-carbon ring where two of the carbon-carbon bonds of the ring are double bonds; the double bonds are separated by a single σ bond, making the double bonds conjugated. Maleic anhydride is has a five-membered ring with ring’s oxygen atom bonded to two acyl groups (R-C=O), and where the R-group is the […]
Written by Lauren ABSTRACT: New carbon-carbon bonds can be formed from a conjugated diene system heated with a dienophile (alkene or alkyne). It is a concerted cycloaddition reaction between the π-electrons of butadiene sulfone and maleic anhydride to form cyclohex-4-ene-1,2-cis-dicarboxylic anhydride. The product doesn’t need to be recrystallized and its purity is confirmed by a melting point test and 1H NMR analysis. INTRODUCTION: The synthesis of new carbon-carbon bonds between butadiene sulfone and maleic anhydride can be achieved through […]
