1H‐NMR Chemical shifts of all‐syn‐1,2,4,5‐tetrafluorocyclohexane (1), all‐syn‐1,2,3,4‐tetrafluorocyclohexane (2), and their complexes with benzene are calculated at the BHandH/6‐311+G(2d,p) level. The observed shielding of certain resonances on going from CD2Cl2to (D8)toluene solution is qualitatively reproduced in these model calculations, in particular when standard B3LYP/def2‐TZVP optimised geometries are employed. The results are interpreted with the quantum theory of atoms in molecules (QTAIM) and non‐covalent interactions (NCI) methods, and they indicate that aromatic molecules bind strongly (1.6 kcal mol−1) to the ‘positive face’ of these molecules. The level of theory is validated for the new compound all‐syn‐1,2,4,5‐tetrafluoro‐3‐phenylcyclohexane (3), where a recently developed QM/MM protocol for optimisation of molecular crystals afforded excellent agreement between the B3LYP/def2‐TZVP structure and that observed in the solid.
