In a second case study, we conducted experiments to demonstrate the application of the reactive in ruthenium-catalyzed ROMP , and these were compared against commercially available monocyclic alkenes which have been explored extensively in ROMP . The oxanorbornenediimides (ONDIs), derived from cycloaddition between furan and maleimide derivatives were of interest since the resultant polymers have been examined as gas transport membranes . We examined how RSE changes with substitution pattern on the bicyclic rings and in particular, how substituents at the 1 and 4 positions influence reactivity in Ru-catalyzed ROMP since substituents at these positions can improve photostability of the resultant polyalkenamer by replacing the allylic C-H bond with a C-C bond .
