Summary:A novel process affords omega-ketocarboxylic acid derivatives of the formula (I) in which R , R , R , and n are as defined in the description by reaction of compounds of the formula (II) with compounds of the formula (III) or with compounds of the formula (IV) in which m is as defined in the description in anhydrous hydrogen fluoride, if appropriate in the presence of boron trifluoride. Novel omega-ketocarboxylic acid derivatives of the formula (If) in which R<1-1>, R<2-1>, R<3-1 >and q are as defined in the description.
