Abstract: The cyclohexanone derivatives 2a, 3a, 4a, and 5a were studied by variable temperature pmr and their behavior was compared to that of the analogous methylenecyclohexane derivatives 2b, 3b, 4b, and 5b. All compounds except 4a gave temperature-dependent spectra which by means of computer spectral simulations allowed the determination of the activation parameters characteristic of chair inversion.
