Abstract: The invention relates to a method for producing chlorocarboxylic acid chlorides of formula (I), wherein R and R , independently from one another, mean a hydrogen atom, an organic radical containing carbon, a halogen, a nitro or cyano group and Y means an alkylene chain having 1 to 10 carbon atoms in the chain which is unsubstituted or is substituted by organic radicals that contain carbon, by halogen, nitro and/or cyano groups, whereby the alkylene chain can be interrupted by an ether-, thioether-, tertiary amino- or keto group, whereby the organic radicals of Y and/or R and/or R can be connected to one another and thereby form a non-aromatic system, whereby said radicals contain carbon, by converting a lactone of formula (II), wherein R , R and Y have the aforementioned meanings, using a hydrogen chloride and phosgene in the presence of a catalyst. Hydrogen chloride is added before and/or while phosgene is added. The hydrogen chloride is only introduced at a temperature of at least 60 DEG C. A pyridine compound is used as the catalyst.

Abstract: The invention relates to a method for producing o-chloromethyl benzoic acid chlorides of formula (I), in which R 1 to R 4 can be the same or different and represent hydrogen C 1 -C 4 alkyl, halogen or trifluoromethyl, by reaction benzo condensed lactones of formula (II), in which R 1 to R 4 have the above-mentioned meaning, with thionyl chloride. The inventive method is characterized in that the reaction is carried out in the presence of catalytic quantities of a Lewis acid and in the presence of catalytic quantities of a phosphine derivative.

Abstract: The invention relates to a method for producing o-chloromethyl benzenecarbon yl chlorides of formula (I), wherein R1-R4 can be the same or different and sta nd for hydrogen, C1-C4-alkyl, halogen or trifluoromethyl, by converting benzocondensed lactones of formula (II), wherein R1-R4 have the aforemention ed meaning, with gaseous or liquid phosgene and the dimers or trimers thereof. The inventive method is characterised in that the conversion is carried out in the presence of catalytical amounts of a Lewis acid and catalytical amounts of a phosgenation catalyst.

Abstract: The invention relates to a method for purifying acid chlorides which have been produced by converting carboxylic acids with carbon oxychloride or thionyl chloride in the presence of a catalyst adduct. The acid chlorides are treated with a hydro halide of carboxylic acid amides of general formula (I), wherein R stands for hydrogen or C1- to C3-alkyl; R and R , independently from one another, mean C1- to C4-alkyl or R and R together mean a C4- or C5-alkylene chain. The thus purified acid chloride is isolated by separation said acid chloride from the carboxylic acid amide hydro halide-phase.
