Written by Hannah Abstract Ring expansion can be achieved through a cyclo addition reaction of a dinophile and a conjugated diene in a concerted reaction where all electrons move at the same time. The experiment takes place in a single step and therefore contamination would stem from overuse of the non-limiting reagent. Cyclohex-4-ene-1,2-cis-dicarboxcylic anhydride was prepared by placing butadiene sulfone (2.0g, 0.0169moles), the diene, with maleic anhydride (1.2g, 0.0122moles), the dinophile, while dissolved in the solvent xylene (.80mL, 0.0075moles) […]
