(DE) VERFAHREN ZUM HERSTELLEN VON ARYL-SUBSTITUIERTEN PYRAZOLEN
(EN) PROCESS FOR PRODUCING ARYL-SUBSTITUTED PYRAZOLES
(FR) PROCÉDÉ DE PRODUCTION DE PYRAZOLES SUBSTITUÉES PAR UN ARYLE
Abstract
(DE)
Die vorliegende Erfindung betrifft ein Verfahren zum Herstellen von 1-Aryl-substituierten Pyrazolen umfassend die Umsetzung von Alkoxyenonen und Enaminoketonen mit Hydrazin-Derivaten zu 1- Aryl-substituierten dihydro-1H Pyrazolen, deren Weiterreaktion unter Wasserabspaltung zu 1-Aryl substituierten -Trihalogenmethylpyrazolen und deren Weiterverarbeitung.
(EN)
The present invention relates to a process for producing 1-aryl-substituted pyrazoles comprising the reaction of alkoxyenones and enaminoketones with hydrazine derivates to form 1-aryl-substituted dihydro-1H pyrazolenes, the further reaction thereof with dehydration to form 1-aryl-substituted trihalogen methylpyrazolene and the further processing thereof.
(FR)
La présente invention concerne un procédé de production de pyrazoles substituées par 1-aryle comprenant la mise en réaction d'alcoxy-énones et d'énaminocétones avec des dérivés d'hydrazine pour obtenir des dihydro-1H-pyrazoles substituées par 1-aryle, leur réaction ultérieure s'accompagnant de la dissociation de l'eau en tri-halogéno-méthyle-pyrazoles substituées par 1-aryle. L'invention concerne également leur retraitement.
