Abstract

The fluorine n.m.r. spectrum of fluorocyclootatetraene has been shown to be temperature dependent between 30 and 65º. This is attributed to changes in the rate of an inversion-bond-shift process which is slow on the n.m.r. time scale at low temperatures. The free energy of activation for inversion is approximately 12 kcal/mole at -33º.
