Réactivité du groupement N-(époxy-2,3 propyl)-N-méthylamino vis-à-vis d'amines aromatiques à l'état fondu. Etude des mécanismes et des chemins réactionnels
Abstract
Mechanism and kinetics of the reactions of N-(2,3-epoxypropyl)-N-methylaniline (1) with aniline or 4,4′-sulfonyldianiline (3) were investigated using high performance liquid chromatography and 13C FT NMR under different conditions (110–172°C). Comparison of 1 with its derivatives shows that the activity of the 2,3-epoxypropyl group in such epoxides depends on the structure and the substituents at the benzene ring; etherification may occur already before the secondary amine is consumed.
