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<1 >and R<2>, independently from one another, mean C1- to C4-alkyl or R<1 >and R<2 >together mean a C4- or C5-alkylene chain. According to the inventive method, hydrogen chloride is added during and/or after the conversion.
