Title
(DE) VERFAHREN ZUR HERSTELLUNG VON FLUORIERTEN MOLEKÜLEN
(EN) PROCESS FOR PREPARING FLUORINATED MOLECULES
(FR) PROCÉDÉ DE FABRICATION DE MOLÉCULES FLUORÉES
Abstract
(DE)
Die vorliegende Erfindung betrifft ein Verfahren zum Herstellen von &agr;-fluorierten Estern aus &agr;-Hydroxyestern durch Umsetzung mit einer Dihalogencarbonylverbindung (oder einem Äquivalent) zu Halogenformiaten und weiter zu Fluorformiaten, die dann in Gegenwart geeigneter Katalysatoren thermisch zersetzt werden. Außerdem betrifft die Erfindung die Einzelschritte des Verfahrens und teilweise neue Fluorformiate.
(EN)
The present invention relates to a process for preparing α-fluorinated esters from α-hydroxy esters by reaction with a dihalocarbonyl compound (or an equivalent) to give haloformates and further to give fluoroformates, which are then decomposed thermally in the presence of suitable catalysts. The invention also relates to the individual steps of the process and in some cases to novel fluoroformates.
(FR)
La présente invention concerne un procédé de fabrication d'esters α-fluorés à partir d'α-hydroxyesters par réaction avec un composé dihalogénocarbonyle (ou un équivalent) pour former des formiates d'halogène, puis des formiates de fluor, qui sont ensuite décomposés thermiquement en présence des catalyseurs appropriés. L'invention concerne également les étapes individuelles du procédé et des formiates de fluor partiellement nouveaux.
