Abstract: The invention relates to a method for producing acid chlorides by converting carboxylic acids with carbon oxychlorides or thionyl chloride in the presence of a catalyst adduct of an N,N-disubstituted formamide of general formula (I) and carbon oxychloride or thionyl chloride. In the formula, R and R , independently from one another, mean C1- to C4-alkyl or R and R together mean a C4- or C5-alkylene chain. According to the inventive method, hydrogen chloride is added during and/or after the conversion.

Abstract: Process for the purification of carbonyl chlorides which have been prepared by reacting carboxylic acids with phosgene or thionyl chloride in the presence of a catalyst adduct, in which the carbonyl chlorides are treated with a hydrohalide of carboxamides of the formula (I)in which R is hydrogen or C1- to C3-alkyl; R and R independently of one another are C1- to C4-alkyl, or R and R together are a C4- or C5-alkylene chain, and the carbonyl chloride purified in this way is isolated by separation off from the carboxamide hydrohalide phase.

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: In a process for chlorinating ketones which, apart from the carbonyl group, are inert in respect of triarylphosphine dichlorides, except for cyclopropyl methyl ketone, in which the ketones are reacted with a chlorinating agent in the presence of triarylphosphine oxides, the amount of triarylphosphine oxide is from 0.1 to 10 mol %, based on the amount of ketone. The ketones preferably have a least one CH-acid proton in the alpha position to the carbonyl group.

Abstract: Production of chloroalkanoyl chlorides (I) with a (substituted) 1-10 carbon (hetero)alkylene chain, by reacting a lactone (II) with a chlorinating agent in the presence of a chlorination catalyst, is carried out in the presence of a boron compound. Production of chloroalkanoyl chlorides of formula (I) with a (substituted) 1-10 carbon (hetero)alkylene chain, by reacting a lactone of formula (II) with a chlorinating agent in the presence of a chlorination catalyst, is carried out in the presence of a boron compound. [Image] R1>, R2>H or R; R : halo, nitro, cyano or an organic group containing carbon; Y : optionally R-substituted 1-10 C alkylene, which may have a (thio)ether, tertiary amino or keto group in the chain; and R groups on Y, R1> and/or R2>can be linked to form a non-aromatic system.

Abstract: The invention relates to a method for producing o-choromethyl benzenecarbonyl chlorides of formula (I), wherein R -R can be the same or different and stand for hydrogen, C1-C4-alkyl, halogen or trifluoromnethyl, by converting benzocondensed lactones of formula (II), wherein R -R have the aforementioned meaning, with gaseous or liquid phosgene and the dimers or trimers thereof. The inventive method is characterized in that the conversion is carried out in the presence of catalytical amounts of a Lewis acid and catalytical amounts of a phosgenation catalyst
