Nuclear Magnetic Resonance Spectroscopy. A Reinvestigation of the Kinetic Parameters for Inversion of 1,2,2-Trimethylaziridine

Abstract

Kinetic parameters for inversion of 1,2,2-trimethylaziridine have been evaluated by the line-shape method for the temperature-dependent nmr spectra of the neat liquid and solutions in acetone, benzene, and chloroform. The previously reported activation energy for inversion of this substance is substantially too low. There appears to be a striking difference in activation energy, but not in rate, for inversion in acetone and in chloroform
