    摘要: 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 further relates to the individual steps of the process and in some cases to novel fluoroformates.
