Popis: The conformational preference for 1,2-difluorocyclohexane has been studied experimentally via NMR spectroscopy and computationally using CCSD/6-311+G(2df,p). The results confirm our previous conclusions that the diaxial conformer of trans-1,2-difluorocyclohexane has the lower energy in the gas phase, whereas the diequatorial conformer has the lower energy in solution. SCIPCM reaction field calculations reproduce the observed solvent effects. The 1,4-difluorocyclohexanes have also been reexamined computationally.
