Abstract

The assessment of weak inter- and intra- molecular C^δ+F^δ-...C^δ+=O^δ- interactions were theoretically evaluated in 4 different sets of compounds at different theoretical levels. Intermolecular CH3F...C=O interactions were stabilizing by ca. 1 kcal mol^-1 for various carbonyl containing functional groups. Intramolecular CF...C=O interactions were also detected in aliphatic and fluorinated cyclohexane carbonyl derivatives. However, the stabilisation provided by intramolecular CF...C=O interactions was not enough to govern the conformational preferences of compounds 2-4.
