Inter- and intramolecular CF···C=O interactions on aliphatic and cyclohexane carbonyl derivatives
Abstract
The assessment of weak inter- and intra- molecular Cδ+Fδ-...Cδ+=Oδ- 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.
