As with carbonates 1a-g, we examined the distribution of relative differences in RCD energy barriers and solvent interaction energy for 2a-ar as compared to 1a (Fig. and). Consistent with what is observed for 1a-g, enthalpic barriers computed using MeCN resulted in nearly all carbonate systems having lower barriers for RCD relative to 1a, with several systems having energy barriers drop by up to 6 kcal/mol (Fig. ). The relative solvent interaction energy in general showed mostly negative values relative to 1a for all solvents, with PhMe seemingly having more values clustered near 0 relative to 1a (Fig. ). This is in line with what is observed for 1a-g where monomers have non-aliphatic side chains having stronger interactions with solvent (Fig. ) considering most of the carbonates 2a-ar have non-aliphatic side chains and tend to have stronger solvent interactions (Fig. , Supplementary Fig. ). As with 1a-g there does not appear to be a direct correlation between enthalpic barrier height, solvent interaction energy, and molecular volume.
