Stéréochimie en série aziridine: VI—Etude en Résonance Magnétique Nucléaire d'alcools aziridiniques primaires (configuration à l'azote,isoméries de rotation)
Authors:Paul Baret  Henri Handel  Jean-Louis Pierre
Abstract:The PMR spectra of six primary aziridinyl carbinols are studied over a temperature range of ?30°C to +100°C. Nitrogen configuration is determined. When the inversion process is effective, kinetic parameters are evaluated. Rotational isomerism about the ‘ring? CH2OH’ bond is studied from vicinal coupling constants associated with the two diastereotopic protons on the ? CH2OH group. From the J(HOCH) coupling constant (in CCL4) rotamer populations of the hydroxyl group are determined in some cases and the overall conformational distribution can be established.
