摘要

The measurement of aryl-naphthyl rotational barriers, Delta G(double dagger), in various solvents for two substituted 1,8-diarylnaphthalenes by dynamic H-1 NMR showed that Delta G(double dagger) trends in aromatic systems can be fully rationalized only when considering the different types of aromatic interactions that can be established in the ground and transition states, namely, intramolecular interactions involving the aromatic rings and specific solvation interactions.
