| Abstract: | Kinetic parameters are obtained for ring inversion of 4-chloro- and 4-bromo-1-methylenecyclohexanes by observation of 13C and 1H NMR spectra as a function of sample temperature. Cl and Br substituents show similar effects on the inversion barrier in the exo-methylene system and in the parent cyclohexane. |
