solution NMR indicate that all-syn 1,3,5-trifluorocyclohexane 5 adopts the expected tri-equatorial conformation, however in the solid state the more polar triaxial conformation is observed. This and the favoured conformations of substituted (Me, OMe, NH(CO)Me, NHBoc) derivatives of 5 are investigated to explore triaxial C–F preferences.
