of the starting materials (EE)-2,4-hexadien-1-ol and maleic anhydride), in the Tandem Green Diels-Alder Reaction were not carefully added in a 1:1 ratio, but rather a 2:1 ratio, how would this impact the proton NMR? And If a different diene was used with a melting point of 100C would you expect this reaction to be successful using a solvent free methodology
