Process for the preparation of alkyl fluorobenzoates of the general formula (I) <IMAGE> in which R represents an alkyl radical and Fn represents 1 to 4 fluorine atoms which, independently of one another, are bonded to the aromatic ring, by reacting a fluorobenzoyl chloride of the general formula (II) <IMAGE> in which Fn has the above-defined meaning with an at least stoichiometric amount of an alkali metal alcoholate ROM in which R has the above-defined meaning and M represents an alkali metal from the group consisting of Li, Na and K, in the corresponding alcohol ROH at temperatures from -10 DEG C to 150 DEG C, if appropriate distilling off the solvent, and removing the alkali metal chloride formed by treating the mixture with water or by filtration. |
