Abstract
The rate of inversion of 7,7-dicyano-2,5-bis(difluoromethyl)norcaradiene (10), presumably by way of its valence tautomer, 7,7-dicyano-2,5-bis(difluoromethyl)cycloheptatrien (11), was studied through the temperature dependence of the magnetic nonequivalence of the gem-fluoro groups. The activation energy E, was found to be 14.6 ± 0.4 kcal/mol and log A is 13.4 ± 0.3.
