Abstract: front page image
(DE)2-Alkyl-3-aryl- oder -heteroaryloxaziridine werden in besonders vorteilhafter Weise hergestellt, wenn man entsprechende N-Alkyl-aryl- oder -heteroarylaldimine mit einer aromatischen Percarbonsäure oder deren Salz in Gegenwart von Wasser einer wasserlöslichen Base und eines mit Wasser mischbaren Lösungsmittels bei Temperaturen unter 30°C oxidiert. So können auch neue 2-Alkyl-3-aryloxaziridine erhalten werden.
(EN)According to the invention, 2-alkyl-3-aryl- or -heteroaryloxaziridines can be produced particularly advantageously by oxidising suitable N-alkyl-aryl- or -heteroarylaldimines with an aromatic percarboxylic acid or its salt in the presence of water, a water-soluble base and a solvent that is miscible with water, at temperatures of less than 30 °C. Novel 2-alkyl-3-aryloxaziridines can also be obtained in this way.
(FR)Selon la présente invention, des 2-alkyl-3-aryl- ou -hétéroaryl oxaziridines sont préparées de manière particulièrement avantageuse grâce à l'oxydation de N-alkyl-aryl- ou -hétéroaryl aldimines correspondantes avec un acide percarboxylique aromatique ou son sel, en présence d'eau, d'une base soluble dans l'eau et d'un solvant miscible avec l'eau, à des températures inférieures à 30 °C. Cela permet également d'obtenir de nouvelles 2-alkyl-3-aryl oxaziridines.
