| Title of Invention | PROCESS FOR PREPARATION OF ALPHA-FLUORINATED ESTERS BY HALOCARBOXYLATION OF LACTIC ACID ESTERS AND SUBSEQUENT DECARBOXYLATION |
|---|---|
| Abstract | 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. (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. |
