Nuclear magnetic resonance spectroscopy. Conformational equilibriums and equilibration of 3,3-difluoro-trans-cyclodecene

Abstract

On cooling 3,3-difluoro-trans-cyclodecene from room temperature to - 152º, three different processes which equilibrate cyclodecene conformations appear to become slow on the nmr time scale. At -152º, at least five out of eight possible conformational classes are present, four of which are separated by 0.8 kcal/mol or less. The free energy of activation for the slowest of the equilibration processes compares well with that for trans-cyclodecene itself.
