molecular balances were designed to study and measure fluorine–aromatic (F–π) interactions. Fluorine substituents gave rise to increasingly more stabilizinginteractions with more electron-deficient aromatic surfaces. The attractive F–π interaction is electrostatically driven and is stronger than other halogen–π interactions.
In order to understand the vital role of the imide substituent, a systematic theoretical DFT study at the PCM/B3LYP/6-31+G(d) level was carried out. We found that substituents at the nitrogen atom of epoxyimides exerted remarkable effects on the regioselectivity in the ethanolysis reaction, based on the solvent effects and intramolecular electronic interactions. Particularly, the preference for the
