The stability differences between the two isomers are further confirmed by their relative energies. The chair configuration is calculated to be 1.83 kcal/mol more stable than the boat isomer, a result that aligns well with earlier theoretical studies, which reported values of 2.06 kcal/mol and 2.10 kcal/mol , whereas the calculation of Hudzik et al is significant . Nevertheless, these studies agree on the fact that exo-TCD-chair is more stable than is boat isomer, although the energy differences obtained need further experimental validation. The combined differences in dipole moment and molecular size, together with relatively high energy barrier likely contribute to the increased stability of the chair form, making it the dominant isomer under typical conditions.
