| Abstract: | The conformational free energies of CN, Cl and COOC2H5 substituents have been evaluated from the PMR spectra of 4-substituted 3,3,6,6-d4-cyclohexene. The PMR spectra of trans-1,2-dicyano-3,3,6,6-d4-cyclohexane permit the conformational equilibrium (in different solvents) and the gauche diequatorial interaction energy between the two CN substituents to be estimated. |
